Effect of friction pressure on the properties of friction welded MA956 iron-based superalloy

Effect of friction pressure on the properties of friction welded hot rolled MA956 iron-based superalloy plate, produced by mechanical alloying, has been investigated. Joining processes were carried out by various friction welding parameters. Tensile strengths and hardness values of the weld interface were determined and the microstructure features of these samples were investigated. Optimum friction pressure for this material was determined.
