Determination of Phase Transformation Point of New Type Ti-5Al-3.3V-8Mo-10Nb-1.0Zr-0.5Cr Alloy
The determination of titanium alloy phase transformation point is very important for phase transformation is the theoretical basis of titanium alloy heat treatment. One new type of titanium alloy Ti-5Al-3.3V-8Mo-10Nb-1.0Zr-0.5Cr was designed and prepared, then the (α + β→β) phase transformation point of this alloy was determined using simulation method, calculation method and continuous heating-up method, and the comparison on these methods has been made in accuracy and simplicity. The phase transformation point was obtained rapidly by simulation method with the value of 806°C, it was obtained by calculation method with the value of 804.28°C, According to the results of software simulation method and calculation method ,the phase transformation point 805 is obtained by the continuous heating-up method. Compared the results of three methods, the results measured by three methods are quite approachable, the phase transformation point was 805±1°C, and the software simulation method is the most accurate and simple.
