SiCw/Al复合材料的研究重点已经转移到应用研究方面。制约其广泛应用的问题是二次加工,该问题的解决是SiCw/Al复合材料迈向广泛应用的关键[1～3]。本文即是针对该复合材料二次加工工艺之一的冷轧变形问题开展的研究。通过冷轧前的预先热挤压变形,实现了SiCw/L3复合材料的大应变
The research focus of SiCw / Al composites has shifted to applied research. The problem that restricts its widespread application is secondary processing. The solution of this problem is the key to the wide application of SiCw / Al composites [1-3]. This article is for the secondary processing of the composite cold-rolling deformation of one of the issues. By pre-hot extrusion deformation before cold rolling, the large strain of SiCw / L3 composites was achieved
