Microstructure and mechanical properties of new metastable β type titanium alloy
چکیده انگلیسی

A new metastable β type titanium alloy called TB-13 with the combination of excellent strength and ductility was developed successfully. In order to develop a perspective on this new alloy, the influence of several commonly used heat treatments on the microstructure and properties was studied. In solution-treated and quenched samples, a low-temperature aging at 480 °C results in the precipitation of finer α phase. The precipitation of coarser α phase plate at higher aging temperature (560 °C) leads to the increase of tensile ductility but reduction of strength. During low-temperature aging at 300 °C, quite homogeneous distribution of fine isothermal ω phase particles was found. The isothermal α phase provides nucleation sites for α phase during two-step aging process and makes α phase extremely fine and disperse uniformly in β matrix. Thus, TB-13 alloy is strengthened and its mechanical properties are improved.
