Abstract
Informations on the transformation behavior of titanium-base alloy during continuous cooling is extremely important for the development of the heat treatments procedure to provide specific mechanical properties. This paper summarizes the continuous cooling transformation diagrams of five kinds of titanium-base binary alloys, Ti-Mo, Ti-V, Ti-Nb, Ti-Al and Ti-Sn.
The specimens were soaked at a suitable temperature under an argon protective atomosphere prior to quenching, which was carried out by argon jet stream. Cooling curves were automatically drawn by recording temperature changes by an electromagnetic oscillograph. From these cooling curves, the continuous cooling transformation diagram was constructed for the respective titanium alloys.
