摘要
系统介绍了大塑性变形(SPD)细化晶粒的条件和目的,综述了4种主要的大塑性变形工艺的基本原理、特点和应用,剖析了细晶材料的强度和超塑性特征,展示了大塑性变形制备细晶材料的诱人前景和发展方向。
The condition and purpose of ultrafine-grained materials fabricated by severe plastic deformation (SPD)are described systematically.Principle,character and application of four SPD techniques are reviewed.Strength and superplasticity of ultrafine-grained materials are also discussed.
