【摘要】 通过拟合不同温度下ｈｃｐ结构金属Ｔｉ的晶格常数和弹性模量，并考虑具有普适性的Ｒｏｓｅ关系，得到了Ｔｉ的温度依赖嵌入原子法（ＥＡＭ）函数．这些不同温度下的ＥＡＭ函数均满足稳定结构条件和Ｃａｕｃｈｙ不等式，从而证明了它们的可靠性．本文结果说明了ＥＡＭ函数同温度有关，并为不同温度下Ｔｉ基金属材料的特性研究提供了相应的Ｔｉ的ＥＡＭ函数．更多还原

【Abstract】 Temperature-dependent embedded-atom-method (EAM) functions of hcp titanium have been determined by fitting to the lattice constants and elastic constants corresponding to various temperatures, and also by considering the universal Rose’s relation. The EAM functions thus obtained satisfy the stable structure requirement and Cauchy discrepancy. This work shows that EAM functions do have temperature-dependence,and provides EAM functions of titanium for the study of Ti-based metallic materials under various temperatures.更多还原
