Abstract

As different friction coefficients, extrusion speeds and extrusion temperatures have an effect on equal channel angular extrusion process of Ti5553 alloy under non-isothermal condition, 3D model had been set up to simulate the high temperature deformation behavior and particle tracking method was given to analyze the equivalent strain of Ti5553 alloy under that environment. The study shows that the maximum equivalent strain reaches 1.2 and occurs at the inside corner of the fan-shaped area. Moreover, when the friction coefficient more than 0, the equivalent strain occurs in advance, the stress of the specimen at the entrance and exit increase and the stress distribution at the corner of the fan-shaped area is more unevenly. When the extrusion speed is 25mm•s-1, the time of the specimen generates the same equivalent strain is shorter, the stress value of the specimen decreases, and the stress distribution of the specimen is more evenly.
