Abstract

A specific wave interface and its formation mechanism in an Al-Fe joint prepared by magnetic pulse welding method are investigated. Specific waves appear occasionally at the interfaces of joints, and the height of the wave peak coincides with the width of the transition zone formed by the enormous force. This work reveals that the specific wave interface is caused by high speed shearing at a certain angle. This shearing process can be classified using Stokes' Theorem, and the Navier-Stokes equation is employed to predict the height of the wave peak to obtain the width of the transition zone.
