【摘要】：利用高温炉对00Cr17Ni14Mo2不锈钢开展了一系列高温下的稳态拉伸试验、瞬态拉伸试验和蠕变试验,测得了不锈钢在不同高温温度下的弹性模量、屈服强度、极限强度、极限应变、伸长率和蠕变应变.利用MATLAB软件对00Cr17Ni14Mo2不锈钢各力学性能(弹性模量、屈服强度、极限强度、极限应变、伸长率)与温度关系曲线和蠕变曲线进行了拟合.结果表明:当应力水平为0.2fu(fu为不锈钢常温极限强度)时,00Cr17Ni14Mo2不锈钢在较高温度(600℃)下的短期蠕变应变相当明显,在钢结构抗火计算时应考虑短期蠕变应变对钢结构响应的影响.所建立的00Cr17Ni14Mo2不锈钢各力学性能与温度关系方程均能较好地拟合试验结果.

The elastic modulus, yield strength and ultimate strain of stainless steel at different temperature were measured. Elongation and creep strain. The mechanical properties (elastic modulus, yield strength, ultimate strain, elongation) of 00Cr17Ni14Mo2 stainless steel were fitted with temperature and creep curves by MATLAB software. The results show that the short term creep strain of 00Cr17Ni14Mo2 stainless steel at higher temperature (600 鈩，
