对挤压效应影响的大量研究,得出了许多重要的理论上的和应用上的结论。然而,这个问题至今尚未解决。不仅如此,这个问题还正在向着非常重大而又有实效的方向发展——即在主要成分相同,热处理制度也相同时,用改变组织状态的方法来提高半成品的强度。本文试图对这方面工作做出某些总结,并拟定出进一步研究的途径和运用所获 A large number of studies on the effects of extrusion have resulted in many important theoretical and practical conclusions. However, this issue has not been solved yet. Not only that, but the problem is also moving in a very significant and effective direction - by changing the state of the organization to increase the strength of the semifinished product when the main components are the same and the heat treatment system is the same. This article attempts to make some summary of the work in this area, and to develop ways and applications for further research
