摘要 参考文献 相关文章 Metrics 全文: PDF(521 KB)   摘要: 本文运用电化学渗透技术研究了18Ni 马氏体时效钢的氢扩散和捕集现象。结果表明,时效试样内存在析出相颗粒,使表观氢扩散系数减小,其原因是析出相界面捕集氢,阻滞了氢输运过程的进行;并发现500℃时效3h 表观扩散系数最小,扩散激活能最大,因为该制度时样品内析出相颗粒的数量最多,分布最弥散,此时的析出相界面捕集能为10.0kJ/mol,陷阱密度(室温时)为3.4×10~(26)/m~3。最后就常规双电解池式的电化学渗透实验,分析和讨论了几个值得注意的问题。 关键词 ： 电化学渗透技术,  表观氢扩散系数,  氢陷阱,  捕集     Abstract：The electrochemical permeation technique was used to study thetrapping and transport phenomena of hydrogen in 18 Ni maraging steel.Theapparent diffusivity decreased as the amount and the density of precipitateinterfaces which act as trapping sites of hydr Key words： dectrochemical permeation technique    apparent diffusivity of hydrogen    hydrogen trap    trapping 收稿日期: 1989-02-25      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 姚大平 陈文绣 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y1989/V3/I1/47 1 Pressouyre G M.Acta Metall,1980;28(7) :895 2 Devanathan M A V and Stachurshi Z.Proc Roy Soc,1962;A270(1) :90 3 姚大平,硕士学位论文,中国科学院金属研究所,1987 4 McNabb A and Foster P K.Trans AIME,1963;227(3) :618 5 Kummick A J and Johnson H H.Acta Metall,1980;28(1) :33 6 叶恒强,邹本三.金属学报,1979;15(1) :69 7 Lee Jong-Lam,Wober J T and Park Jong-ki.Scr Metall,1986;20(6) :823 8 冼爱平,李培基,王仪康,李薰.金属学报,1988;22(3) :A181 9 Sherman Robert and Birnbaum H K.Metall Trans,1983;14(A):203 10 Pressouyre G M and Bernstein I M.Metall Trans.1978:9A(11) :157 [1] 徐坚;孙秀魁;陈文绣;李依依.
