Summary: The present research developed an Al-based composite using the stir-casting method, which faced challenges in conventional machining, leading to the adoption of a non-traditional machining process. Response surface methodology (RSM) was used to design the experimental plan, and the obtained data was optimized using complex proportional assessment (COPRAS) and machine learning methods. The optimized settings predicted the highest material removal rate (MRR) at 1.11 g/s and tool wear rate (TWR) at 0.0114 g/s.

Summary: This study focuses on the direct fabrication of graded composites using cold spraying technique and explores the impact of different hard-phase powder sizes on composite formation. The results indicate that well-consolidated microstructures with uniform reinforcement distribution can be achieved with fine hard-phase powder, while coarse hard-phase powder leads to less homogeneous layer build-up.

Summary: Accumulative Roll Bonding (ARB) is an expensive technique due to the large number of controlling parameters, but a response surface methodology is used in this study to analyze the interaction effect between ARB parameters on the tensile strength and hardness of composite sheets. By investigating the microstructure, phase analysis, and mechanical properties of ARBed AA1050 composite sheets produced with different passes and SiC content, the significance of ARB parameters on the properties of the composites is confirmed.

Summary: The study prepared 50 vol% SiC/Al composites with different SiC particle size and Al alloy composition using Spark Plasma Sintering. The thermal properties, microstructures, and interface reaction products of the composites were investigated. The optimization of composite components and sintering process parameters were conducted. It was found that SiC particle size and sintering process parameters were crucial for obtaining high thermal-mechanical properties of the composites. The best physical properties were achieved in the 16 μm SiC/6061Al composites sintered at 50 MPa, 8 min, and 520°C, with bending strength of 649 MPa, thermal conductivity of 189 W/(m·K), and coefficient of thermal expansion of 7.9×10-6 K-1 at 50-100°C. XRD and SEM analysis revealed the absence of hazardous reaction product Al4C3 at the interface and the growth of MgAl2O4 and Mg2Si together at the interface.

Summary: Electronic packaging materials should possess excellent overall performance in thermal, mechanical, and machinability to meet the challenges of the highly integrated development of the electronics industry. Low-temperature sintering of high-strength 3D-SiC frameworks and fabrication of 3D-interpenetrated network structures SiC/Al composites were achieved. Increasing coarse powder size improved the thermal conductivity, coefficient of thermal expansion, and thermal deformation parameter of the composites, but further increasing coarse powder size reduced the mechanical properties. The composites maintained stable thermal conductivity and coefficient of thermal expansion after 100 thermal cycles, ensuring long-term service reliability.

Summary: Carbon Fiber Reinforced Plastics (CFRP) have poor machining performances using conventional drilling techniques due to their anisotropy and inhomogeneity. In this study, a micro fluid-assisted laser-induced plasma drilling (MFA-LIPMD) method was proposed to reduce taper and heat-affected zone (HAZ). The MFA-LIPMD process showed advantages over laser in the air (LIA) and laser-induced plasma drilling (LIPMD) in terms of smaller taper, reduced thermal damage, and improved mechanical properties.
