Abstract The tensile strengths of the duplex microstructural BT25Y titanium alloys with different contents of Al, W, and Mo have been measured at room and high temperatures. According to Kolachev' formula, the equivalent formulae of yield strength and ultimate tensile strength were derived with the experimental results. The calculated strengths from these equivalent formulae also accord with the experimental values of BT25Y titanium alloys with widmanstatten microstructure at variant temperatures.

Key words: BT25Y titanium alloy strength equivalent formula
