| Abstract Scope |
Carbon steel with elongated pearlite shows preferable resistance against hydrogen embrittlement. Consequently, the elongated pearlite is possibly an alternative for martensite as the fundamental microstructure for high-strength steel. The most significant difference between elongated pearlite and martensite lies in the anisotropy of strength due to these microstructure morphologies. In this work, the anisotropy of yield stress was studied with the spring steel bar (0.53wt%C) having the elongated pearlite evolved by a caliber rolling. The compression tests were conducted at various loading axes. The rolled steel showed ~1.5 GPa yield strength in the rolling direction. With the loading axis deviating more from the rolling direction, the yield strength decreases gradually and reaches ~200 MPa smaller at the loading axis perpendicular to the elongated direction. The origin of this anisotropy will be discussed with various data, such as texture. |
