AbstractThere are many discrepancies in the literatures concerning the martensite constitution in the alpha +beta double phase titanium alloys after quenching, so the Ti-4Al-4.5Mo alloy was selected to analysis further the martensite phase transformation in the alloy. The results show that when the quenching temperature is above the (alpha+beta)/beta transformation temperature (925 degrees C), the hexagonal martensite (alpha') formed. With the decrease of quenching temperature, another kind of martensite with orthorhombic structure (alpha '') appeared which can coexist with alpha' in a certain temperature range. In the sample quenched at 800 degrees C, the alpha '' disappeared, and the alloy only contains alpha and beta phases. The alpha '' martensite reduced the hardness of martensite transformed structure remarkably EDS analysis indicated that the content of beta stabilized element (Mo) is not the only factor determining the martensitic type.
