in thixoforging process At the end of simulation of thixoforging process, five points are found in the part,as shown in Fig.4. Fig.4 Schematic of intercept points Fig.5 shows the curves of temperatures at different points. It is included that the temperature of the part decreases with the stage of thixoforging. The velocity of temperature decreases the fastest at Point P3. Points P1 and P2......

">A thixoforging process of the 9Cr18 steel was conducted in a designed setup, and a kind of multi-diameter component was fabricated. The effects of the forming temperature and the strain rate on the solid-/liquid-phase flow behavior were discussed. The results showed that functional gradient properties of the 9Cr18 steel could be obtained after thixoforging. Changes of microstructure along radial direction......
