Abstract：The TTT- curves and kinectic parameters of metallic glass Zr_(75.9)Ni_24.1) have been determined in both isothermal and non-isothermal (continuance scanning) crystallization processes. By means of peak analysis of DSC and the sequent data treatment with a computer program, the overall effective activation energy E= 224～194 kJ/mol and the reaction order n=3.38-3.77 have been obtained respectively. It is suggested that the process in discussion is characterized by eutectic growth with a decreasing nucleation rate. This is in agreement with the results of X-ray diffraction studies reported by Altounian et al. and present authors. A brief discussion about the isothermal and non-isothermal analysis used here and given. 收稿日期: 1987-02-18      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 张其瑞 曹致玉 H.C.Freyhardt 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I2/206 1 张其瑞,Freyhardt H C.低温物理,1984;6:93 2 Zhang Q R, Kerbs H U, Freyhardt H C.
