The temperature was monitored by infrared spectrometer within ±2℃. Calculational results indicate that the activation energy is 84.8 kJ / mol and activation volume is 0.754 nm_3. The creep friction stresses are 127, 115, 95.6 and 90.3 MPa at 1900, 2050, 2200 and 2350℃ respectively. By extrapolation of the temperature dependence upon zero creep friction stress, the temperature seems to be about 3375℃ just to approach the sublimation one of carbon.(Correspondent: QIAO Shengru, associate professor, Faculty No.401, Northwestern Polytechnical University,Xi'an 710072 ) Key words： unidirectional carbon/carbon composite    high temperature creep    creep friction stress    creep activation energy    creep activation volume      基金资助:国家自然科学基金;;航空基金 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 乔生儒 骆蓉 杨峥 康沫狂 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1994/V30/I23/524 1BuckleyJD．ceramBull,1988;67(2):3642FitzerE．Carbon．1987;25:1633SinesG,YangZ,VikersBD．Carbon,1989:27:4034SinesG,YangZ,VikersBD．ActaMetall,1989;37:26735SinesG,YangZ,VikersBD．JAmCeramSoc,1989;72(1):546HawthorneHM,JMaterSci,1976;(11):97 [1] 侯介山; 张玉龙; 郭建亭; 冀; 光; 周兰章; 叶恒强 . 铸造镍基合金K44的高温蠕变行为[J]. 金属学报, 2004, 40(6): 579-.
