Influence of Annealing Treatment on the Microstructure and Mechanical Properties of TaW12Alloy AITranslate
Abstract AITranslate
Annealing was done on TaWl2 alloy tensile samples at 1 340-1 430 ℃ ,and investigations were made on the rule of change of their room temperature mechanical properties with the annealing mode. The microstructure and fracture morphology of the annealed samples were observed by metallurgical micro- scope and scanning electron microscope. The results show that the annealed sample at 1 340 ℃ has tensile strength of 730 MPa and yield strength of 660 MPa. And the annealed sample at 1 430 ℃ has tensile strength of 660 MPa and yield strength of 550 MPa. The strength of the alloy decreases with annealing temperature increasing,but remains at a high level. The elongation rate of the alloy increases from 32% to 45% with the increase of annealing temperature, indicating obviously improved plasticity. The annealed tensile sample at 1 430 ℃ has obvious necking phenomenon,and its shrinkage rate reaches the maximum value. The final suitable annealing mode is （1 400-1 430 ℃）×2 h for TAW12 alloy.
