Influence of metal-ceramic interfaces on the behaviour of metal matrix composites and their joints

摘要

The present contribution emphasises the importance of the chemical reactions which occur during the fabrication and joining procedures, in the metallic matrix/ceramic reinforcement interfaces of the metal matrix composites. Using both the experimental data obtained by other investigators studding metal/ceramic systems such us Al/SiC, Al-Mg/Al_2O_3, Ti/SiC, etc.; and the results of the research carried out for the present authors in the diffusion bonding of Al/SiC and Al-Mg/Al_2O_3 composites, the nature of these chemical reactions and their influence on the MMC properties are discussed.
