Finite element modeling of the linear friction welding of GH4169 superalloy

Materials & Design, 2015
Abstract In the present paper, finite element method (FEM) simulation of linear friction welding (LFW) GH4169 superalloy was carried out using ABAQUS software. The friction coefficients of GH4169 superalloy under different parameters (friction load, friction velocity and specimen temperature) were obtained using the friction and wear experiments.
