摘要
12Cr1MoV/T23异种钢焊接较多应用于火电厂的管道中。通过对不同焊后热处理的异种钢焊接接头金相组织和力学性能的研究,发现合适的热处理工艺能优化焊接接头的微观组织,并改善其室温力学性能。
The heterogeneous steel pipe welding joints of 12Cr1MoV/T23 are widely used in thermal power plants. By comparing microstructuros and mechanical properties of three different heat - treatment pipe joints, the result showed that heat treatment with temperature at 730℃could optimize the microstructure and improve the room temperature mechanical properties.
