Effect of Deformation Temperature on Microstructure and Properties of Gradient Extrusion of TB8 Titanium Alloy AITranslate
Abstract AITranslate
To study the influence role of deformation temperature on the gradient microstructure and pro-perties of TB8 titanium alloy,gradient extrusion tests were conducted on TB8 titanium alloy at 850℃,900℃and 950℃,and the variation laws of microstructure and microhardness of specimens at different deformation temperatures were investigated by OM and XRD.The experimental results show that after gradient extrusion,the specimen can be divided into three deformation zones,including the core micro-defor-mation zone,the sub-center medium deformation zone,and the edge large deformation zone,showing a gradient distribution of the grain size gradually decreasing from the core to the edge.After the gradient extrusion and deformation,the sub-grain size of the material decreases while its microscopic strain and dislocation density increase significantly;decreasing the deformation temperature can significantly refine the grains and increase the overall hardness value.The hardness of the specimen edge at 850℃increases by 16.32%compared with that of the core.
