Determination of Phase Transformation Point of New Type Ti-5Al-3.3V-8Mo-10Nb-1.0Zr-0.5Cr Alloy

Abstract:

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.
