The habit plane of larme-llar carbide is {111}_γ. The distribution of N_2 changes no more before or after thelarmellar cell precipitated. The diffusion activation energy of carbon reducesremarkably with the increase of N_2 content. It is believed that the larmellar carbi-de is harmful to the high temperature creep and impact properties of the alloy. Key words:  HK50 alloy      larmellar carbide      habit plane      diffusion activation energy      Received:  18 February 1990      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1990/V26/I2/16 1 石子源,于永泗,曹智本,王焕庭.金属热处理,1986;(12) :33 2 高温合金(冶金学和生产)编辑组.高温合金(冶金学和生产),上海:科学技术文献出版社,1980:174 3 Pak H-R, Chang S N, Kato M.
