THE EXPERIMENTAL SIGNIFICANCE OF ENHANCING TITANIUM ALLOY NANOCOMPOSITES MADE BY SELECTIVE LASER ADDITIVE MANUFACTURING AND EXTRACTING BIO-SILICA FROM CALOTROPIS GIGANTEA B. SANDHYA RANI, V. SURESH, M. VAMSI KRISHNA, V. NAVEENPRABHU Surface Review and Letters, 2025 In the present applications in aerospace, landscapes, and automobiles there is a notable demand for lightweight and highly durable materials due to the increased and improved system efficiency. In the present situation, composite materials, especially metal matrix composites, can achieve certain physical, chemical, mechanical, and tribological properties. In this investigation, Calotropis gigantea agricultural waste is utilized to extract bio-silica nanoparticles, which are subsequently incorporated into the titanium alloy matrix materials as nanoreinforcing materials. A simple but effective manufacturing technique to make titanium alloy matrix (Ti)/bio-silica (BS) nanocomposites is selective laser melting. The specimen consists of four various blends of a titanium (Ti) alloy matrix with a base matrix alloy (100[Formula: see text]wt.%) and BS (2.25, 4.5, and 6.75[Formula: see text]wt.%). Investigation and comparison with the fundamental matrix alloy were conducted on the effect on mechanical properties, including density, porosity, microhardness, and tensile strength. With the assistance of elemental mapping, microstructure and energy-dispersive X-ray spectroscopy (EDAX), field emission scanning electron microscopy (FESEM) can be utilized to study rupture processes and worn surface analysis of tensile and wear specimens. The findings show that, when compared to base alloys and other composites, Ti/6.75[Formula: see text]wt.% BS composite has superior mechanical properties.
Optimization of Material Removal Rate and Electrode Wear Rate in EDM Machining of D2 Steel Using Al–Cu–SiC Nanocomposite Powder Metallurgy Electrodes: a Taguchi and ANN-based Approach K. Reetabai, V. Naveenprabhu, Rajesh Mohan, Vinitha Nithianantharaj, Venkat Prasat Sridhar, S. Naveen, Justin Sam George Journal of Environmental Nanotechnology, 2024 In this research study, a novel Al–Cu–SiC composite tool, created using the powder metallurgy (P/M) technique, was used for the electrical discharge machining of D2 steel, and the effects of important process parameters were investigated. The experimental runs were organized using a Taguchi-based design, and prediction models were constructed using artificial neural network techniques. This study was focused on machining performance, employing material removal rate (MRR) and electrode wear rate (EWR) as essential performance indicators and peak current, dielectric flushing pressure, and pulse on time as crucial input parameters. To evaluate the significance and suitability of the regression models created, an Analysis of Variance was conducted. The results showed that Al–Cu–SiC P/M electrodes were more sensitive to peak current and pulse duration. Increasing pulse duration significantly influenced MRR and EWR, with optimal values (MRR of 0.5880 g/min and minimal EWR) attained at a current of 9 A and a pulse length of 80 μs. Taguchi analysis identified pulse duration as the primary determinant; Regression equations emphasized pulse duration and current as critical factors for MRR, whereas ANN optimization effectively forecasted EDM results (R > 0.97), demonstrating decreased errors and reliable model performance across datasets.
Microstructure, Worn Surface, Wear Assessment and Taguchi's Approach of Titanium Alloy Hybrid Metal Matrix Composites for Automotive Applications S. C. V. Ramana Murty Naidu, N. Kalidas, Sivaraman Venkatachalam, Srinivasnaik Mukuloth, Abdul Rab Asary, V. Naveenprabhu, R. Vishnu, Suresh Vellingiri SAE Technical Papers, 2024 <div class="section abstract"><div class="htmlview paragraph">Lightweight materials are in great demand in the automotive sector to enhance system performance. The automotive sector uses composite materials to strengthen the physical and mechanical qualities of light weight materials and to improve their functionality. Automotive elements such as the body shell, braking system, steering, engine, battery, seat, dashboard, bumper, wheel, door panelling, and gearbox are made of lightweight materials. Lightweight automotive metals are gradually replacing low-carbon steel and cast iron in automobile manufacture. Aluminium alloys, Magnesium alloys, Titanium alloys, advanced high-strength steel, Ultra-high strength steel, carbon fiber-reinforced polymers, and polymer composites are examples of materials used for light weighing or automobile decreased weight. The ever-present demand for fuel-efficient and ecologically friendly transport vehicles has heightened awareness of lowering weight and performance development. Titanium alloys properties are increasing in the variety of applications in automotive parts such as fuel tanks, exhaust pipes, engine parts such as connecting rods, engine valves, reinforcing and stiffening parts, sub frames, body panels, fuel cell components, and electrification components. Motorcycles and automobiles that demand high dynamic performance, such as racing cars and bikes, commercial vehicles, and cargo trucks, must increase time on the circuit and have a good reaction. As a result, titanium alloys are frequently used to significantly reduce weight while increasing the performance output of automotive systems. The innovative investigation of titanium metal matrix (Ti-6Al-4V) composite with added multi reinforcement of tungsten carbide particles (WCp) and graphite particles (Grp) were examined on its tribological behavior. The Ti-6Al-4V built-in different composites Ti-6Al-4V/4%WCp/4%Gr and Ti-6Al- 4V/8%WCp/8%Gr with a size of WCp and Gr was 44μm and 15μm invented through stir casting. The investigations were carried out as wear experiments using a pin-on-disc tribometer in dry sliding circumstances at three distinct load (15N, 20N, 25N), sliding distance (1000m, 2000m, 3000m), and sliding velocity (2.5m/s, 4.5m/s, 6.5m/s). The significance of various strictures on wear analysis was investigated using Taguchi’s L27 orthogonal array approach. The findings of Taguchi’s and design of experiment show that the variables most likely to have an impact on wear loss is load, sliding distance, and sliding velocity. The composites bonding structure and wear surface were examined using an optical microscope and a field emission scanning electron microscope. The wear tests reveal that the treated Titanium alloy hybrid metal matrix composites with tungsten carbide and graphite particles have excellent wear qualities with a sliding velocity of 6.5 m/s and a load of up to 35 N in the region with the lowest wear loss of 0.039mm<sup>3</sup>/m. This study adds additional data to the dry slide wear resistance of composite consisting of Ti-6Al-4V alloy and reinforced through WCp with Grp, which are ideal for usage in automotive and transportation applications. The automotive industries employed dynamic conditions resulting in wear loss. To reduce wear and increase vehicle economy and performance, the tribological behavior was researched.</div></div>

Experimental Analysis of EDM Parameters on D2 Die Steel Using Nano-aluminum Composite Electrodes Y. Justin Raj, A. Bovas Herbert Bejaxhin, R. Madhumitha, A. S. Anitha, Hitesh Gehani, Aslam Abdullah, V. Naveenprabhu Journal of Environmental Nanotechnology, 2024 This paper presents an experimental study on the electrical discharge machining (EDM) of AISI D2 die steel using an Al-Ni composite electrode. The investigation focuses on the influence of input parameters like current, pulse duration, and pulse interval, on key output parameters such as material removal rate (MRR), tool wear rate (TWR), and surface roughness (SR). EDM oil was employed as the dielectric fluid. Grey relational analysis (GRA) was utilized for designing and conducting the experiments using the Taguchi L9 method. The ANN model showed excellent predictive accuracy with a perfect correlation coefficient (R) of 1.00, indicating strong capability in forecasting MRR based on machining parameters. GRA further confirmed that higher current settings and longer pulse-off times effectively reduce tool wear, suggesting that the ANN model accurately reflects the conditions that minimize TWR. The ANN model achieved strong predictive accuracy for SR, with high correlation coefficients, although with slightly higher mean squared error (MSE) in testing.
