体心立方金属的固有位错内耗

体心立方金属的固有位错内耗 A BRIEF REVIEW OF THE INTRINSIC DISLOCATION RELAXATION OF b. c. c. TRANSITION METALS 丁棣华 Ding Dihua and Zhou Rusong first-author 周如松 本文试图对体心立方过渡金属的固有位错内耗研究状况作一简要介绍。作者将这个课题的研究进展分为三个阶段,总结了α峰和γ峰的主要实验规律,讨论了这两峰的机制,其中简要地介绍了关于b.c.c.晶体中螺位错特征的较新理论。 The present work presents a brief review of the state of achievements of the studies on the intrinsic dislocation relaxation of b. c. c, transition metals. The progress of this topic is being divided into three periods. A summary of the general riles of α-and γ-peak is drawn from the main experimental results available in literature and mechanisms are discussed. Finally, an attempt is made to introduce briefly the more recent theory on the features of screw dislocation in b. c. c. Crystals. 1982-03-01 2021-04-01 3
