عنوان انگلیسی Finite Element Analysis of Phase Distribution in Forging of the Two-Phase Ti-6Al-4V Alloy to have a Hip Joint Implant
چکیده انگلیسی مقاله In this research, the finite element analysis (FEA) of the effect of forging parameters including temperature, strain rate and cooling rate on the percentage of α and β phases in forging of the two-phase Ti-6Al-4V alloy to fabricate a hip joint implant was investigated. In order to be used in FEA, the stress-strain curves of Ti-6Al-4V at temperatures ranged between 800 to 1000°C and, strain rates of 0.01, 0.1, 1 s-1 up to a total strain of 0.45 by using hot compression test were obtained. The force-displacement curve of hot compression test of a cylindrical sample made of Ti-6Al-4V alloy from FEA and experiment in similar condition was used for verification. Results showed that all three input variables have an effect on the volume percentage of final α and β phases. By increasing the cooling rate, forging temperature and strain rate, the percentage of the final α phase decreases and the amount of the β phase increases. Additionally, in all cooling rates, the amount of the final α phase decreases from the center to the sides of samples.
