The present work is aimed at studying the impact behaviour of commercially available Aluminum matrix composites, in a temperature interval ranging from 25 °C to 200 °C. The results of instrumented impact tests and of microstructural and fractographic observations are correlated with the tensile properties of these materials. A description of the phenomena involved (particles cracking, interfacial failure associated to matrix-reinforcement reaction layers, ductile behaviour of the matrix) is given. The effect of testing temperature as well as that of the matrix characteristics are presented and discussed.

Abstract
The present work is aimed at studying the impact behaviour of commercially available Aluminum matrix composites, in a temperature interval ranging from 25 °C to 200 °C. The results of instrumented impact tests and of microstructural and fractographic observations are correlated with the tensile properties of these materials. A description of the phenomena involved (particles cracking, interfacial failure associated to matrix-reinforcement reaction layers, ductile behaviour of the matrix) is given. The effect of testing temperature as well as that of the matrix characteristics are presented and discussed.File in questo prodotto:
