Al–Si Alloys as a Model System for Damage Accumulation in Composite Materials

The effect of reinforcement characteristics on the damage of composite materials has been investigated on a model Al–Si alloy. Alloy microstructure and damage were described quantitatively in the bulk material by metallographic evaluation of samples cut from the deformed material and using stereological methods. Yield stress, work hardening rate and ductility were assessed by conventional mechanical tests. Optical and scanning electron …
