The invention provides a thermal treatment method for a Ti53311S titanium alloy, in particular to a thermal treatment method for improving the 550 DEG C high temperature mechanical performance of a near-alpha type Ti53311S titanium alloy, which is characterized in that the thermal treatment process is divided into two stages: the first stage is the thermal treatment at the temperature of 930-980 DEG C, the insulating time is 30-90min, and the cooling mode is water cooling; the second stage is the thermal treatment at the temperature of 540-580 DEG C, the insulating time is 4-8h, and the cooling mode is air cooling. In the thermal treatment process, the accumulated deformation of titanium alloy hot working is larger than 95 percent, the forging temperature of the finished product is controlled inside alpha plus beta phrase regions, and the finish-forging temperature is higher than 900 DEG C. The adoption of the thermal treatment method of the invention can realize the Ti53311S titanium alloy ...
