摘要

The purpose of present study is to investigate the effect of neighboring grain on the slip behavior near an interface in high-cycle fatigue. A push-pull fatigue test is carried out for a two-phase (α/γ) stainless steel bicrystal, which consists of ferritic (Fe30Cr) and austenitic (Fe15Cr15Ni) single crystals, with a longitudinal interface. Since the yield stress of α-phase is much higher than that of γ-phase, the crystallographic slip takes place only in the γ-phase. Not only primary slip lines expected by the Schmid factor, but also additional slip lines are observed near the interface of γ-phase. The stress field in the bicrystal is calculated by a finite element method (FEM). The analysis shows that the characteristic slip behavior near the interface is governed by the resolved shear stress on the specific slip system, which increases due to the deformation-constraint by the neighboring crystal.
