Superplasticity of 10CrNi3MoV Steel

摘要: 通过恒温拉伸试验测定了10CrNi3MoV钢在室温至1 000℃温度范围内的延伸率和强度,并借助热膨胀法测定了试验钢的相变特征温度A c1和A c3。结果表明,10CrNi3MoV钢在720~750℃温度区间内断后延伸率超过100%,表现出超塑性行为;其中720℃时塑性最好,断后延伸率达到123.5%,该温度略高于A c1温度。

Abstract: The values of strength and elongation of 10CrNi3MoV steel were obtained by thermostatic tensile test at temperature from room temperature to 1000℃.At the same time, the phase transition temperatures A_c1 and A_c3 of the steel were tested by thermal expansion method.The results show that the 10CrNi3MoV steel performs superplasticity and has elongation more than 100% at 720 ℃~750 ℃, reaching up to 123.5% at 720 ℃, which is slightly higher than that at A_c1 temperature.
