Experimental and Simulation Aspects Regarding LM6/Sicp Composite Plastic Deformation under Different Frictional Conditions

Introduction

Composite materials offer superior properties to conventional alloys for various applications as they have high stiffness, strength and wear resistance. The development of these materials started with the production of continuous fiber-reinforced composites. The high cost and difficulty of processing these composites restricted their applications and led to the development of discontinuously reinforced composites. Discontinuously reinforced composites have found commercial use in some applications, and among these, particle-reinforced composites are likely to reach the largest commercial application stage with their low cost, ease of fabrication, and improved properties. Particulate metal matrix composites can be produced economically by conventional casting techniques, and they usually posses higher elastic modulus and strength values after reinforcement. As the stiffness and strength are increased, a substantial decrease in ductility is obtained.
