摘要：
Two model Al-1%Si alloys have been used in a study focused on the influence of reinforcing particles characteristics on the mechanical properties of composite materials. The microstructure of two alloys containing Si plate-like dispersoids was investigated using quantitative metallography supported by image analysis and stereological methods. Particle fracture was monitored during composite deformation by means of acoustic emission and after deformation by metallographic analysis. Relations between size, shape and probability of cracking of particles were found. The coarse elongated particles damage preferentially. Material failure takes place when the critical volume fraction of broken particles is reached. The amplitude of acoustic emission signal from plastically deformed composite is proportional to the volume of broken particles.
