Abstract Aluminium-based Surface Composites (SCs) fabricated through Friction Stir Process (FSP) with excellent hardness and impact strength are predominantly suited for piston skirt applications. This paves the way for the exploration of multipass effects in steel slag-reinforced AA7075 SCs for analysis of microstructure, hardness and impact strength. Microstructural examination reveals the homogenous distribution of steel slag particulates on the matrix and on increasing the number of FSP passes, the grain size is reduced. Furthermore, a clear interface is obtained between the reinforcements and base AA7075 matrix identified through the macrostructure. X-Ray Diffraction technique (XRD) and Elemental mapping with Energy Dispersive Spectroscopy (EDS) confirm the existence and dispersion of reinforcing constituents available in the composite layer. The superior microhardness along with prodigious impact strength are accomplished in the third pass. The obtained hardness results are attributed to the reduced grain size with decreased oxide content. The enhanced tendency of the reinforcements to blockade the crack initiation and its propagation results in high-impact strength. In addition, the fractography of impact testing specimens is evaluated through SEM and reveals that the ductile mechanism is a dominant failure mode.

Abstract In this research, a novel aluminium metal matrix composite (AMMC) was developed using recycled aluminium alloy as a matrix with 5% alumina as reinforcement. The machining experiments were conducted by varying the input parameters such as voltage (V s ), wire feed rate (F w ), current (I p ), pulse on time (ON T ) and pulse off time (OFF T ), on wire breakage. The effect of voltage level and wire breakage frequency was analysed. The parameter combinations for machining the slot of size 5 mm width and 10 mm height with high machining rate (MR) and less surface roughness (R a ) were analysed using the CRiteria Importance Through Intercriteria Correlation (CRITIC) and simple additive weighting (SAW) methods. The wire breakage frequency is lesser at minimum peak current. The optimal parameter combination for higher MR and lower R a is found to be at 30 V, 7 mm/min, 30 A, 120 μs (ON T ) and 70 μs (OFF T ). Analysis of variance (ANOVA) is performed to understand the significant factors affecting the WEDM process. ANOVA results predict that wire feed rate and voltage contribute 47.82% and 21.23%, respectively, to MR; and pulse on time shows a 23.06% influence on surface roughness. Scanning electron microscopy (SEM) was used to ascertain the pattern of wire breakage in WEDM, and based on the results obtained from employing this technique, it is inferred that the erosion and breakage of the wire are not instantaneous and that a cone shape is formed on the either portion of the wire.

The advance of aluminum alloy-based matrix composites is becoming indispensable in several applications like automobiles, aerospace, electronics, and structural industries due to the benefits over conventional materials such as lightweight, high strength, and high hardness value. The main aim of the work is to study the thermomechanical characteristics (heat transfer rate, convective heat transfer coefficient, and tensile strength) of an aluminum (AA7075) alloy nanocomposite containing 0 wt%, 3 wt%, 6 wt%, and 9 wt% of nano SiC particles (50 nm) by the stir casting technique. The thermomechanical performance of AA7075 alloy nanocomposite is obtained by pin fin apparatus and followed by ASTM test standards. The composite contained 9 wt% nano SiC and was found to have superior thermomechanical characteristics.

Marine corals are mainly composed of calcium carbonate and organic matrix, which can be used as filler in polymer composites thus consequential in waste utilization from aquaculture by-products. In the present study, epoxy resin (EP) matrix composites were prepared by reinforcing raw cuttlebone particles (CB), heat treated cuttlebone particles (HB) as well as commercial calcium carbonate particles (CC) at 10 wt%. Different forms of reinforcement materials were characterized by thermogravimetric analysis (TGA) and X-ray photoelectron spectroscopy (XPS) to confirm the polymorph transformation. Thermal stability and glass transition temperature of EP, EP/CB, EP/HB and EP/CC composites were investigated by TGA and differential scanning calorimetry (DSC). EP/CC composite had highest glass transition temperature than EP, EP/CB and EP/HB composites, but EP/CB and EP/HB had good thermal stability than EP and EP/CC composites.Marine corals are mainly composed of calcium carbonate and organic matrix, which can be used as filler in polymer composites thus consequential in waste utilization from aquaculture by-products.

Using sea coral as a new bio-mass in processing of particle-filled polymer composites is very promising in the field of structural applications. In this study, waste cuttlebone was used as a filler material in epoxy composites. In general, cuttlebone particles derived from crushing and sieving were in aragonite polymorph form. In the present study, calcite polymorph form was obtained after heat treatment of cuttlebone particles at 400℃. Presence of polymorph form, elemental composition and thermal stability were confirmed with different characterization techniques. Composites were prepared with aragonite and calcite polymorph form cuttlebone particles and commercially available calcium carbonate as reinforcement in epoxy matrix. Tensile tests were carried out to determine the composites strength and compared with predefined theoretical models. Heat-treated cuttlebone reinforced epoxy composites showed higher tensile properties and better interaction between filler and matrix than other composites.
