Phase diagram investigation of the Cu–Sn system was carried out on twenty Cu-rich samples by thermal analysis (DTA), metallographic methods (EPMA/SEM-EDX) and crystallographic analysis (powder XRD, high temperature powder XRD). One main issue in this work was to investigate the high temperature...
The 15th National Conference of Phase Diagrams of China and Multilateral Symposium 011 Phase Diagrams and Materials Design Cu.Sn二元系统相图的第一性原理研究 周伟,穆文凯,刘卫芳,刘立娟,吴萍 (天津大学理学院物理系,天津300072) 摘要:Sn基合金是目前微电子封装领域使用的的主要材料,但目前对于二元Cu-Sn系统研...
一般来说是一个常量,但是在Cu/Sn反应过程中由于Gibbs-Thomson效应的影响,Sn/Cu6Sn5界面趋向于存在一个最低的界面能,这会导致在钎焊过程中 γSn/Cu6Sn5的不断减小,也就是钎焊30 min时 γSn/Cu6Sn5值要大于钎焊60 min时的值. 根据式 (1)可以推断出钎焊30 min时φSn/Cu6Sn5值要大于钎焊60 min时的值,所...

For a particle radius of 10 nm the eutectic point is found at a temperature of 193.9 °C and a composition of Sn-1.8 wt% Ag-0.7 wt% Cu. This shift toward the Sn-rich corner of the phase diagram is roughly consistent with the model proposed by Lee et al. [38] for binary alloys,...
