Abstract：The strain ageing of a-titanium under the influence of an applied stress has been studied. The kinetics of strain ageing obeys the following equation where n=2,; is the increase in flow stress σ_f due to strain ageing; n_0 is the original concentration of solute; n_∞ is the maximum concentration of solute segregated in the dislocations; D is the diffusion coefficient of solute atoms; U_m is the binding energy between a solute atom and a dislocation; b is the Burgers vector; t is the ageing time, k Boltzmann constant and T the absolute temperature. The activation energy of strain ageing obtained is about 1.30±0.15 eV. The strain ageing of α-titanium is very probably due to the presence of both iron as the substitutional atoms and oxygen as the interstitial atoms. 收稿日期: 1965-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王其闵 章熙康 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1965/V8/I4/484 [1] Nabarro, F.
