in annealing temperature range of 150-300 ℃. Then the effects of the different annealed microstructures on high-temperature deformation behavior were further studied. The results indicate that the initial... deformation was analyzed. The results reveal that intergranular cavities with fine size and homogeneous distribution are beneficial to superplastic deformation. Key words: fine-grained 5083 Al alloy; annealing......
Flow behavior of Ti-46.2Al-2.5V-1.0Cr-0.3Ni alloy in secondary hot deformation SI Jia-yong(司家勇), HAN Peng-biao(韩鹏彪), CHANG Xia(昌 霞), ZHANG Ji(张 继) High Temperature Material Research Division... was investigated by the isothermal compression experiments. The direction of secondary hot deformation was taken to be vertical to the former forging axis. And the deformation activation energy......
