ON THE RELATIONSHIP BETWEEN THE EMBEDDED-ATOMMETHOD FUNCTION OF TITANIUM AND TEMPERATURE

Temperature - dependent Embedded-Atom-Method (EAM) function of hcp titanium have been determined by fitting to the lattice constants and elastic constants measured at various temperatures as well as 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 in the meanwhile it also provides EAM functions of titanium for the study of Ti-based metallic materials at various temperatures.
