摘要
强塑性变形(SPD)技术已成为21世纪获得微米、甚至纳米级细晶粒材料,在塑韧性损失不大的情况下成倍提高金属材料强度的手段。概要介绍了目前国内外开发的强塑性变形的新技术或新方法,指出,应力或塑性变形将成为今后改变材料组织性能的主要技术之一,将与热处理技术并驾齐驱。应力热处理专业将成为材料科学与工程中一个新型的专业。
Severe plastic deformation(SPD)technique has become a means of obtaining submicron-scale, even nano-scale grained materials.By using this technique,the strength of metallic materials can he double enhanced without much loss of ductility.In this paper,the recent development of this technique is briefly introduced.It is also pointed out that stress or plastic deformation will become one of major techniques of changing the microstructures and properties of materials and will keep abreast with heat treatment.Stress-heat treatment will be a new special field of study in materials science and engineering.
