Data of the paper "Hot deformation behavior and microstructure evolution of Ti-6Al-9Zr-3.88Sn-1.59W-1.21Nb-0.28Si high-temperature titanium alloy used at 750ºC"

The Ti9ZrWSi alloy utilized in this paper, which can withstand 750℃ for a short time, is a new near-alpha, high-temperature, titanium alloy. The high-temperature properties of this alloy were investigated, and the ultimate tensile strength value achieved was 647.5MPa and the ductility was 38.2% at 750℃ and a strain rate of 5x10-3s-1. The strengthening mechanism of this alloy at 750℃was studied.
