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.
