| Research Abstract |
Using friction welding, the material of a upper part of piston would substitute A6061 by drawing process for AC8A by casting in order to improve durability of the piston subjected to thermo-mechanical cyclic loading. Authors have developed the evaluation method for a joining strength and the way of structural analysis of piston. Moreover, suitable joining conditions of friction welding between contact surfaces with different shape have completely investigated.
