摘要
本文介绍了超塑性研究的进展和在工艺与理论上取得的重要成果。对超塑性研究指出三个重要方向。对超塑性变形提出“显微多重效应”的可能性和合金按相数和两相强度分类进行机理研究。
This paper introduces the advances in research of superplasticity and the most important achievements in technology and theory.Three important dire- ctions for future investigation in superplasticity are proposed.A feasibility of the “micro-multiplicity effect” for superplastic deformation and a research on mechanism according to the number and different strengths of the phases in alloys are also proposed.
