Influence of Heat Treatment on Oxygen Content and Mechanical Properties of TaW10 Alloy Fabricated by Hot Isostatic Pressing AITranslate
Abstract AITranslate
TaW10 alloy was fabricated by hot isostatic pressing with hydrogenation-dehydrogenation powder as the raw material. And then TaW10 alloy was subjected to heat treatment at 1 800-2 200 ℃.The relationships between heat treatment temperature and oxygen content or mechanical properties of TaW10 alloy were studied. The results show that with heat treatment temperature improved, the fracture mode of TaW10 alloy changes from brittle cleavage fracture to brittle intergranular fracture and then to ductile dimple fracture. The strength increases firstly and then decreases with heat treatment temperature improved, and reaches the highest value at 2 100℃.When the heat treatment temperature is up to 2 150 C,TaW10 alloy starts to show ductile deformation characteristics. TaW10 alloy has sharply declined oxygen content after heat treatment at 2 000 ℃,and then there is no obvious change of oxygen content with further im- proved heat treatment tempreature. TAW10 alloy has good strength and ductility only when its oxygen content is sufficiently low and its heat treatment temperature is above 2 150 ℃
