It is found that the yield temperature of the specimens increases markedly with heating rates. The effects caused by mechanical and metallurgical properties under rapid heating of metals are also investigated. An extended Johnson-Mehl equation of recrystallization is derived to include the effects of heating rates. A new concept of upper and lower limits of yield temperature is put forward for a metal under various heating rates.(Correspondent: Dr. LIU Zongde, Department of Mechunics, Peking University, Beijing 100871) Key words:  heating rates      thermo-softening      recrystallization      yield temperature      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/Y1995/V31/I19/329 1陈裕泽．1993年激光的热和力学效应学术会议文集．长沙,1993:1272刘宗德．1994年激光的热和力学效应学术会议文集,海南,1994:13PeterHassen．PhysicalMetallurgy,CambridgeUniv．Press,1978( [1] ZHAO Peng, XIE Guang, DUAN Huichao, ZHANG Jian, DU Kui.
