Diffusion coefficients of some solutes in fcc and liquid Al: critical evaluation and correlation
Yong Du,Yong Du,Y. A. Chang,Baiyun Huang,Weiping Gong,Zhanpeng Jin,Honghui Xu,Zhaohui Yuan,Yong Liu,Yuehui He,F.-Y. Xie +10 more
TL;DR: In this article, the diffusion coefficients of several transition elements (Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) and a few non-transition elements (Mg, Si, Ga, and Ge) in fcc and liquid Al are critically reviewed and assessed by means of the least-squares method and semi-empirical correlations.
Journal ArticleDOI
PANDAT software with PanEngine, PanOptimizer and PanPrecipitation for multi-component phase diagram calculation and materials property simulation
Weisheng Cao,Shuanglin Chen,Fan Zhang,K. Wu,Ying Yang,Y. A. Chang,Rainer Schmid-Fetzer,W. A. Oates +7 more
TL;DR: The newly enhanced PANDAT, integrating PanEngine, PanOptimizer and PanPrecipitation, bridges thermodynamic calculation, property optimization, and kinetic simulation of multi-component systems based on CALPHAD (CALculation of PHAse Diagram) approach.
Journal ArticleDOI
Thermodynamic Assessment and Calculation of the Ti-Al System
TL;DR: In this article, three different analytical descriptions were used to describe the three different types of phases occurring in the Ti-Al system: the stoichiometric compounds, the disordered solution phases, and the ordered inter-metallic compounds which have homogeneity ranges.
Journal ArticleDOI
The PANDAT software package and its applications
Shuanglin Chen,S. Daniel,Fan Zhang,Y. A. Chang,Xinyan Yan,Fanyou Xie,Rainer Schmid-Fetzer,W. A. Oates +7 more
TL;DR: The features of PANDAT, a software package for multicomponent phase diagram calculation, and its calculation engine, PanEngine, are discussed.
Journal ArticleDOI
Temperature Dependence of the Elastic Constants of Cu, Ag, and Au above Room Temperature
Y. A. Chang,L. Himmel +1 more
TL;DR: In this paper, the adiabatic elastic constants c44, ½(c11−c12), and ½ (c11+c12+2c44) have been measured for copper, silver, and gold over the temperature range from 300° to about 800°K using the conventional ultrasonic pulse-echo technique.
