Effect of Cold Deformation and Annealing on Microstructure and Mechanical Properties of Ta-2.5W Alloy AITranslate
Abstract AITranslate
Ta-2.5 W alloy was subjected to room temperature compression and annealing, and the influence of deformation degree and annealing process on the microstructure and mechanical properties of the alloy was investigated by scanning electron microscope and microhardness tester.The experimental results show that when the annealing process is the same(1 350 ℃× 60 min),with alloy deformation degree increa-sing, the recrystallization degree increases, and the grains gradually become more uniform and finer.When the cold deformation degree of Ta-2.5 W alloy is 70%,in the temperature range of 1 200~1 350 ℃ for the holding time of 5~60 min, both increasing the temperature and prolonging the holding time are beneficial to obtain fine grains, and the average grain size of Ta-2.5 W alloy can be finally refined from the original 90 μm to 32 μm.
