摘要

A series of design parameters related to the properties of single-phase BCC multicomponent titanium alloys were introduced in this work. Five multicomponent Ti-V-Mo-Cr-Fe-Zr-Al alloys were melted, and SEM-EDS, EBSD, and TEM characterization results showed that all the solution-treated alloys were single-phase alloys with BCC structure. In order to investigate the relationship between the tensile properties of the design parameters of multicomponent titanium alloys, room temperature tensile performance tests were conducted on the five alloys. Based on the tensile properties, we used correlation analysis and GM (1, N) model in gray system theory to calculate the correlation between various design parameters and properties, and simulated the relationship between alloy design parameters and the properties of multicomponent titanium alloys.
