| Abstract: | Using Inconel718 as the interlayer, we achieved the three-body friction welding of TiAl to 42CrMo, with the joint tensile strength attaining 360 MPa or so. The mathematic model between the interlayer thickness and the tensile strength is set up through digital approximation, we also analysed the joint framework theoretically. |
