Abstract:

The deformation degree,annealing temperature,the variation regularities of deformation characteristic,microstructure and properties of Ti-4Al-22V alloy were studied.The results show that the alloy has good cold workability and wider annealing temperature range.The strength and plasticity of the alloy sheet can be improved by grain size decreasing.
