| Abstract: | By using thermal simulation technique and computer simulation, the conventional canned forging process of TiAl base alloy was studied. The effect of can parameters on the mechanical behavior of TiAl alloys with different H/D ratios was analyzed in this process. The results show that, the peak stress of TiAl base alloy without canning is far higher than that with canning. Compared with the samples with the same H/D ratio, the peak stress decreases with increasing can thickness; while compared with the samples with the same can thickness, the peak stress decreases with increasing H/D ratio. The decrease of the true stress of TiAl base alloy with canning were analyzed according to the theory of plastic deformation and results of computer simulation. |
