摘要：

(alpha+beta)/beta phase transformation temperature of a TC11 titanium alloy was confirmed to be 1035 degrees C, which was obtained by three methods including the calculation method, differential scanning calorimetry and metallographic techniques. Based on this result, annealing treatments below and above the (alpha+beta)/beta phase transformation temperature were carried out, and the microstructure of the TC11 alloys before and after annealing treatment was analyzed by SEM. The result showed that conventional annealing below 1035 degrees C does not change the Widmanstaten structure of TC11 alloy, though the thickness of alpha lamellar structure becomes thicker with increasing the annealing temperature. The microstructure of the TC11 alloy treated by annealing above the (alpha+beta/beta transformation temperature is non-uniform because of the different forming temperature and growing duration of cc phase in the TC11 alloy. https://www.scientific.net/SSP.127.91.pdf
