Abstract:
This article investigated the anisotropic microstructure and mechanical properties of 1050 wheel steel. The tensile test for standard round bar specimens with 0°, 30° and 45°three different angles to rolling direction of cool rolling 1050 steel round bar after hot treatment were carried out at room temperature. And the impact toughness test for Charpy-U notched specimens with 0°, 15°, 30° and 45° four different angles to rolling direction were carried out at room temperature. The results showed that the homogeneity of microstructure decreased with increasing angle to rolling direction. The tensile properties decreased with increasing angle to rolling direction. The percentages of decline for yield strength and extension strength were 10.3% and 7.4% respectively and all fracture were ductile fracture. The impact toughness decreased with increasing angle to rolling direction and the percentages of decline for impact absorbing energy was 27%.
