Abstract: The reinforcement particles play important roles in determining microstructural development and properties of Al6061 composites. In the present work, the aging behavior of Al6061 reinforced with Y2O3 and TiC particles produced via mechanical alloying are investigated. The results indicate that the peak-aged Al6061 alloy without reinforcement demonstrates the highest hardness, which co...

In this paper, an experiment is conducted to optimize the kerf width of wire electrical discharge machining (WEDM) on Aluminum hybrid composite with Zinc coated brass wire using Taguchi method. Aluminum metal matrix composites (MMCs) reinforced with silicon carbide particulate (SiCp) find several applications due to their improved mechanical properties for a wide variety of aerospace and automo...

The failure of an AL6061-T6 and Kevlar-29 composite plate under high-velocity impact from an S-S (structural Steel) projectile tool was investigated using the nonlinear explicit finite element software, ANSYS AUTODYAN. Two velocity ranges 350 m/s and 700 m/s were used for FEM simulation. It was analyzed that AL6061-T6 is more resistant than KELVAR 29 at both ranges but Kevlar 29 is light in wei...
