The Ti17(α + β)-Ti17(β) dual alloy-dual property blisk produced using Linear Friction Welding (LFW) is considered as high-performance component in advanced aeroengine. However, up to now, microstructure evolution and relationship between micro mechanical properties of LFWed β)/Ti17(β) dissimilar joint have not been thoroughly revealed. In this work, complex analyses the phase transformation mechanisms are conducted, transformations individual zones correlated their microhardness...
Numerical simulation and experimental research on Linear Friction Welding (LFW) for GH4169 superalloy were carried out. Based the joint microstructure mechanical properties, a suitable welding process was determined, which provided an important theoretical basis manufacture repair of aeroengine components such as blisk. The results show that strain rate gradually increases with increase frequency, deformation resistance thermoplastic metal in process, resulting interface not being extruded...
The blisk composed of Ti2AlNb intermetallic alloy and Ti60 titanium with its dual properties is considered as the ideal high-performance component in advanced aeroengines. There are incompatibilities at interface during welding using conventional fusion techniques like electron beam. In this work, dissimilar joint was successfully produced employing linear friction welding, a whose strength over that base metal obtained. intergrowth bonding mechanism promoted by combined effects dynamic...
Linear Friction Welding (LFW) technology was used to realize the welding of GH4169 superalloy, and effect parameters on microstructure, mechanical properties corrosion behavior joint analyzed. The results show that there is a positive correlation between weld hardness tensile strength. With gradual increase heat input pressure, quality gradually improved, but affected zone not significantly increased. smaller grain size weld, higher strength plasticity joint. shortening amount, resistance...
Linear friction welding (LFW) method is a solid-state manufacturing process. In the present study, GH4169 superalloy was welded using LFW method. Macro morphology and shortening of joints were investigated to understand effect variables on geometric parameters such as joint shape size. Detailed microstructural mechanical property material microstructure well properties. Compared with raw material, grains are refined, tensile strength under two sets greater than that material.
