The T_g and T_c as well as the activation energy of glass transition are all increased with the increase of atomic radius of the extra metal added, but the activation energy of crystallization is in opposite way. A correlation between the enthalpy change and the peak of damping was also observed. The above results may be valuable to the non-crystalline glass designer. 收稿日期: 1984-04-18      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 余赋生 李建国 严言忠 张延忠 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I4/313 1 Masumoto, T.; Maddin, R., Mater.
