The effect of Cu concentration on tensile and compression properties of Ti-۱۰Mo alloy using molecular dynamics simulations

Titanium alloys have been extensively explored and fabricated for application in several engineering fields. Its superior mechanical properties, Ti-۱۰Mo-xCu alloy has potential applications in hip implants. Determining mechanical qualities via experimental methods takes a long time, especially when carried out in compression and tensile testing. Therefore, material design modeling using an MD simulation method approach is used to evaluate the mechanical properties of the compression and tensile tests of the Ti-۱۰Mo-xCu alloy. In this research, material design through computer modeling is carried out at ۳۰۰ K in the x <۱۰۰> direction of the Ti-۱۰Mo alloy with the addition of Cu composition at ۳, ۶, and ۹ wt.% to evaluate the properties of the alloy. The simulation results of the Cu addition produces maximum stresses of ۶۰۳, ۱۶۰, and ۲۳۶ Mpa, respectively. The experimental method in the compression test shows a decrease in the maximum stress after adding Cu to the Ti-۱۰Mo alloy. It has the same trend value as the compression test outcomes on the experiment and MD simulation method. The result of tensile strength for the Ti-۱۰Mo-xCu alloy are ۷۰۵۶.۸, ۷۲۳۸.۲, and ۷۴۳۳.۱ Mpa, respectively. MD simulation of the results of crack propagation in tensile strength is successfully performed based on the increase at high strain until plasticity occurs in the alloy.
