主 题:friction welding duplex stainless steel hardness toughness microstructure
摘 要:Friction welding is a solid-state joining process which is applied extensively because of its advantages such as low heat input,efficient application,ease in manufacturing,and environmental *** present study investigates the mechanical and metallurgical properties of UNS S32205 duplex stainless steel friction-welded *** process parameters,namely friction pressure,upsetting pressure,and rotational speed are individually varied from low level to high level(within the range of the machine setup)and their effects on the joint properties are *** partial-deformation zone had higher hardness than the weld and base *** toughness of the joints was evaluated at room temperature and at subzero temperature *** impact toughness of the friction-welded joints was found to be superior to fusion-joined duplex stainless steel in room and cryogenic conditions.
