Abstract

We investigated the deformation of the worked materials in the punching of slanted fine holes in austenitic stainless-steel SUS304 sheets. We observed the microstructure and hardness distribution of the cross section of the worked material, and then, considered the material flow. The material flow changed the complexity of what as a result of the influence of work hardening or the transformation to strain-induced martensite. Then, the direction and magnitude of the pressure applied to the punch also changed such inn a complex manner. However, the worked material almost flowed into the hole of the die. Then, the punch was carried into the hole by this material flow.
