The machinery method of the pushing and extruding of bend has become the most advanced manufacturing process of a brupt bend, because it possesses peculiar advantages which are quite beyond comparison with hot impact and press bend. On the basis of succeeding in carrying out the new process of the pushing and extruding of bend, we have made some researches in the test of the pushed and extruded bend deformation. Something about the proc- ess, Iaw and temperature condition of the defoemation of bend is known. In the paper, an initial study is made from the view point of practice.
