摘要：

The mathematical models have been established to describe the temperature and stress profiles in Ti6Al4V cylinder during quenching. The residual stress and deformation of the workpiece can be predicted precisely based on ANSYS software. The simulated results show that the temperature of the divided element decreases faster at the edge than that at the internal of the workpiece during quenching from 1050 to 20 degrees C. The largest temperature difference and dimension change in diameter are about 90 degrees C and -0.935%, respectively. The position of largest tensile stress occurs around the edge of the cylinder.
