  • Additive Manufacturing of Tungsten Carbide (WC)-Based Cemented Carbides and Niobium Carbide (NbC)-Based Cermets with High Binder Content via Laser Powder Bed Fusion
    Fabio Miranda, Marcelo Otavio dos Santos, Rodrigo Condotta, Nathalia Marina Gonçalves Pereira, Daniel Rodrigues, et al.
    Metals, 2024
    The additive manufacturing technique performed via laser powder bed fusion has matured as a technology for manufacturing cemented carbide parts. The parts are built by additive consolidation of thin layers of a WC and Co mixture using a laser, depending on the power and scanning speed, making it possible to create small, complex parts with different geometries. NbC-based cermets, as the main phase, can replace WC-based cemented carbides for some applications. Issues related to the high costs and dependence on imports have made WC and Co powders emerge as critical raw materials. Furthermore, avoiding manufacturing workers’ health problems and occupational diseases is a positive advantage of replacing WC with NbC and alternative binder phases. This work used WC and NbC as the main carbides and three binders: 100% Ni, 100% Co, and 50Ni/50Co wt.%. For the flowability and spreadability of the powders of WC- and NbC-based alloy mixtures in the powder bed with high cohesiveness, it was necessary to build a vibrating container with a pneumatic turbine ranging from 460 to 520 Hz. Concurrently, compaction was promoted by a compacting system. The thin deposition layers of the mixtures were applied uniformly and were well distributed in the powder bed to minimize the defects and cracks during the direct sintering of the samples. The parameters of the L-PBF process varied, with laser scanning speeds from 25 to 125 mm.s─1 and laser power from 50 to 125 W. Microstructural aspects and the properties obtained are presented and discussed, seeking to establish the relationships between the L-PBF process variables and compare them with the liquid phase sintering technique.
  • Numerical and Experimental Analysis of the Influence of Manufacturing Parameters in Additive Manufacturing SLM-PBF on Residual Stress and Thermal Distortion in Parts of Titanium Alloy Ti6Al4V
    M. O. Santos, A. S. F. R. Maiolini, F. Miranda, A. Farias, V. Seriacopi, et al.
    Lecture Notes in Mechanical Engineering, 2024
    Additive manufacturing (AM) has become popular in recent years due to its integration with Industry 4.0 and for enabling the production of complex and optimized geometries. However, the process leads to disadvantages, such as thermal distortions and the generation of residual stresses due to thermal gradients during the parts production. Based on these undesirable characteristics, this work aims to model AM numerically through the Finite Element Method (FEM), besides obtaining experimental results that relate the impact of different process parameters, such as laser power, speed, and hatch distance on the residual stress and distortions distribution, to parts generated by Selective Laser Melting (SLM)—Powder Bed Fusion (PBF)—of titanium alloy Ti6Al4V. The experimental tests, as well as the numerical analyses, followed a factorial design. The results for thermal distortions are excellent with differences below 4.5% between the manufactured and simulated parts. As for the results of residual stresses measured at a single point on the lateral face, for most of the results, the difference was less than 4%; however, there was a large dispersion of results. When the values of average residual stresses were considered in the simulation, the results had statistical relevance and showed greater robustness. It was found that the average diameter of Ti6Al4V titanium parts was greatly influenced by the laser power followed by the hatch distance. The increase in power increased the average diameter of the samples, while the increase in speed and hatch decreased their diameter. In turn, increasing laser power decreased residual stress, while increasing speed and hatch tended to increase the mean residual stress.
  • Gelcasting Of Nbc20ni Cemented Carbide
    Daniel Rodrigues, Suzilene Real Janasi, Fábio Miranda, Fernando dos Santos Ortega
    Euro Powder Metallurgy 2023 Congress and Exhibition Pm 2023, 2023
    Gelcasting has been successfully used to produce high-performance sintered ceramic components, and large shrinkages during sintering at high temperatures are common for obtaining high-density parts, since very fine ceramic powders are used as raw material. The same approach can be applied for cemented carbides (hardmetals), and near net shaped parts can be produced using moulds and, if necessary, additional turning operations before sintering can be used. Fine niobium carbide, nickel and tungsten carbide powders were used to produce aqueous slurries, which were adjusted to mold samples to obtain sintered cemented carbides with homogeneous microstructure and with a good combination of hardness and toughness. The slurry stability was investigated mainly considering the loading of solids. The nature and amounts of monomers, dispersants and additives were also investigated. Samples and prototypes were sintered at high temperature in vacuum, and characteristics such as density, microstructure and hardness were evaluated.
  • NbC-BASED CERMET PRODUCTION COMPARISON: L-PBF ADDITIVE MANUFACTURING VERSUS CONVENTIONAL LPS POWDER METALLURGY
    Fabio Miranda, Marcelo Otavio Dos Santos, Daniel Rodrigues, Rodrigo Santiago Coelho, Gilmar Ferreira Batalha
    Materiali in Tehnologije, 2023
    The production of carbide parts (cermet) by additive manufacturing, such as laser powder bed fusion (L-PBF), has been a great challenge due to the complex optimization of process parameters to improve density, porosity, microcracks or abnormal growth of grains and obtain a microstructure as homogeneous as possible. This work aims to compare the evolution of the microstructure when using the conventional route of powder metallurgy, i.e., liquid phase sintering (LPS) with the L-PBF direct additive manufacturing process, considering the NbC-based carbide material. Sample compositions were prepared in w/%, samples were compacted under 50–125 MPa, without polymeric binders, and they were sintered under a vacuum at temperatures of 1330 °C and 1370 °C. For the L-PBF process, a vibrating device made it possible to improve the fluidity of the mixtures of three alloys, NbC–30Co, NbC–30Ni and NbC–30(Co, Ni). The mixtures exhibited low sphericity, low fluidity and compressibility, which were improved with a roller compactor. Thin powder mixture deposition layers were evenly applied and well distributed across the powder bed to avoid defects and cracks during sintering. The L-PBF process parameters varied including a power of 50–125 W and a laser scanning speed of 25–125 mm·s–1. Different microstructures, identified with a light microscope (LM) and a scanning electron microscope (SEM), and properties obtained with the two processes, direct (L–PBF) and indirect sintering (LPS), were compared.
  • WC Cemented Carbides: Microstructural Aspects Comparing L-Pbf Additive Manufacture And Convencional Lps
    F. Miranda, M. O. dos Santos, D. Rodrigues, G. F. Batalha, S.R. Janasi, et al.
    Euro Powder Metallurgy 2023 Congress and Exhibition Pm 2023, 2023
    This work aims to compare the conventional powder metallurgy (PM), via Liquid Phase Sintering (LPS), with additive manufacture (AM), via L-PBF (Laser Powder Bed Fusion), considering WC cemented carbides and binders like Co, Ni and mixtures of Co and Ni. The mixtures were produced from dried slurries and some powder agglomeration was obtained with the use of organic binder. The great challenge was to improve flowability to obtain a bed as homogeneous as possible, so, additionally, a vibrating container was used to spread powder trying an uniform layer. Conventional samples were produced by press and high temperature vacuum sintering. For AM, laser power versus velocity were investigated. Microstructures were evaluated considering carbide distribution and the presence of cracks and porosities. The effects of different metallic binders were presented and discussed.

  • The influence of the sintering temperature on the grain growth of tungsten carbide in the composite WC-8Ni
    Fabio Miranda, Daniel Rodrigues, F.Y. Nakamato, C. Frajuca, G.A. Santos
    Materials Science Forum, 2017
    This study aims to highlight the grains growth of tungsten carbide in the nickel binder phase, in function of sintering temperature of a hot isostatic pressed - HIP (at 60 bar) material, targeting the morphological behavior of the grain size and densification of the composite WC-8Ni. Cylindrical samples 25 mm x 15 mm were sintered in compression at temperatures ranging from 1380 °C to 1460 °C. The results showed that increasing the sintering temperature, there is an increase in WC grain size, the hardness decreases and the porosity is reduced increasing the specific gravity.
  • Microstructural Evolution of Composite 8 WC-(Co, Ni): Effect of the addition of SiC
    Fabio Miranda, Daniel Rodrigues, Francisco Yastami Nakamoto, Carlos Frajuca, Givanildo Alves dos Santos, et al.
    Defect and Diffusion Forum, 2016
    Tungsten carbide (WC) based cemented carbides, also called hardmetals, are a family of composite materials consisting of carbide ceramic particles embedded in a metallic binder. They are classified as metal matrix composites (MMCs) because the metallic binder is the matrix that holds the bulk material together [1]. WC based composites are used in applications where a good combination of hardness and toughness are necessary [2]. It is usual to add more components to tailor the microstructure of the WC-(Co, Ni) system. The hardness for the cemented carbides based on nickel, increases significantly because of the addition of reinforcements like SiC nanowhisker [3]. In this work, the SiC was considered as an additional component for the composite WC-8(Co, Ni). Four mixtures were prepared with SiC contents ranging from 0 to 3.0 wt%. These mixtures were pressed (200 MPa) and green samples with 25.2 mm of diameter and 40 g were produced. Sintering was carried out in Sinter-HIP furnace (20 bar). Two sintering temperatures were investigated, i.e. 1380 and 1420oC, and the sintering time considered was 60 minutes. The relative density, hardness, linear and volumetric shrinkage were determined. Microstructural evaluation was investigated by optical microscopy and scanning electron microscopy (SEM-FEG). The results showed that the addition of SiC promoted higher densification and grain size growth. The hardness was higher for samples with SiC, so solid solution hardening of the binder was more effective than WC grain size growth.
