【摘要】 研究了55SiMnVB钢淬火回火状态的应力-应变行为。结果表明:在280～520℃回火温度范围内呈应变软化,软化程度随回火温度而异,高于400℃回火,动态屈服强度随回火上升呈线性地下降。更多还原

【Abstract】 The stress-strain behaviour of 55SiMnVB steel after quenching and tempering has been investigated. The results show that 55SiMnVB steel demonstrates softening in the tempering temperature range of 280-520℃, and the degree of softening is dependent upon tempering temperatures. When the steel is tempered above 400℃, dynamic yield strength linearly decreased with increasing tempering temperatures.更多还原
