Abstract

Development of new alloys has been slowed by the empirical method of trials and errors that absorbs more and more resources and leads to ever smaller results. Solution of this problem is possible through the use of the general principles of the alloys design theory. In this paper, we have proposed to consider cast metal matrix composites as foundry alloys and have developed a methodological approach to selection of alloying and reinforcing components considering the operational conditions for parts of friction units. Application of the proposed approach allows to make reasonable choice of composite alloys components within conditions of various schemes of reinforcing, including exogenously reinforced, endogenously reinforced and complex reinforced alloys.
