一、前言随着航空航天技术的高速发展,对材料的机械性能要求越来越高,因而新材料研究不断发展。复合材料具有能够发挥其组成材料的协同作用,同时又有很大的材料设计自由度,因此具有较大的发展优势。SiC_w晶须增强6061Al复合材料是近年来发展起来的新型材料,屈服强度(σ_(0.2))是这种材料设计和制造的重要强度指标之一。本文试图建立挤压态SiC_w/6061Al I. Introduction With the rapid development of aerospace technology, the mechanical properties of the material requirements are getting higher and higher, so the continuous development of new materials research. Composites have the synergistic effect of being able to exert their constituent materials, and at the same time, they have great freedom of material design and therefore have great development advantages. SiC_w Whisker Reinforced 6061Al Composites are new materials developed in recent years. The yield strength (σ_ (0.2)) is one of the important strength indexes for the design and manufacture of this material. This article attempts to establish extruded SiC_w / 6061Al
