INTERACTION BETWEEN Cu AND LIQUID Sn(II)——SEM OBSERVATION OF INTERMETALLIC GROWTH

ZHANG Qiyun , LIU Shuqi , XU Yaping Peking University , Beijing , China professor , Department of Chemistry , Peking University , Beijing , 100871 , China

金属学报(英文版)

The features of Cu_6Sn_5 growing slowly at lower temperature and growing rapidly up over 350℃,and or Cu_3Sn growing at higher temperatures,bave been detailedly observed under SEM.The increase of Pb content seems to inhibit sequentially the growth of Cu_6Sn_5 in Pb-Sn alloy....

A New Model for Predicting Ternary Thermodynamic Properties of Solution Phase and Its Application

Zhiyu QIAO Xianran XING Shuzhen DUAN University of Science and Technology Beijing , Beijing , 100083 , ChinaChaogui ZHENG Beijing University , Beijing , 100871 , China

材料科学技术（英文）

A new geometric asymmetric model for predicting the thermodynamic properties of ternary system from three sub-binaries is presented in this paper.Its analytical expression with good calculating ac- curacy is most simple in all asymmetric models.The new model was applied to predict the enthalpies of ...
