内容説明

The aim of this volume is two-fold. Firstly, to give a current overview on silicide-based structural materials and identify important and promising future research directions. Secondly, it is intended to serve as a catalyst for the expansion of research and development activities in this new field, promoting rapid technology transfer to private industry. Elevated temperature structural materials represent a key enabling technology for many aspects of advanced aerospace, automotive, energy and environmental systems. High temperature structural silicides constitute an important new class of such materials. Central aspects for the development of structural silicides are improvements in both high and low temperature mechanical properties, with retention of oxidation resistance. Recent composite and alloying approaches have demonstrated significant success in addressing these issues. The optimum development of structural silicides requires the combined efforts of both ceramists and metallurgists owing to their mixed metallic - covalent - ionic atomic bonding state. The contents of this volume will be of interest to both the metallurgical and ceramics communities.
