Fatigue of particle-and whisker-reinforced metal-matrix composites

摘要: Abstract The reinforcement of metallic alloys with ceramic particles or whiskers has generated a new family composite materials. They have matured during the last 20 years, and are currently used in structural components subjected to cyclic loads. This was partially possible thanks large research effort aimed at characterizing their behavior fatigue. results this activity constitute fairly coherent body which relates micromechanisms deformation overall fatigue performance. presented review, is divided seven sections. After introduction, microstructural changes induced by dispersion reinforcements described. followed two sections devoted an analysis from mechanical viewpoints. next focused on origins crack nucleation kinetics propagation upon performance these composites examined part, emphasizes advantages limitations as compared unreinforced counterparts. effects processing, thermo-mechanical treatments, features, environmental factors loading conditions included each section provide comprehensive picture composites.
