Abstract

Abstract

In the present study, the compression experiments with compression deformation of 10%, 20%, 30%, 50% and 70% were carried out for the nearly α type TA18 titanium alloy bars after radial precision forging and hot rolling. The bars were subsequently annealed for 2 hours at 510 ℃. The influence of compression deformation on the microstructure and mechanical properties was investigated by metallographic microscopy. It is found that the radial precision forged and hot rolled TA18 alloy bars can achieve uniform microstructure after compress experiments with compression deformation of 10%, 20%, 30%. The mechanical properties of the alloy bars after radial precision forging and hot rolling keep basically consistent and the compressive strength gets a maximum value at the compression deformation of 30%. The grain size and distribution of the compressed alloy bars are still relatively uniform after annealing at 510 ℃ for 2 hours. After annealing, the microstructure of the compressed radial precision forging bar is more uniform.
