采用直接热轧法成功获得了Cu-P-Cr-Ni-Mo双相耐候钢,研究了热轧双相耐候钢的组织、力学性能、腐蚀性能及焊接性能。结果表明:Cu-P-Cr-Ni-Mo热轧双相耐候钢组织均由多边形铁素体及其上分布的不规则的马氏体岛组成;相对于Cu-P-Cr-Ni-Mo耐候钢的常规热轧态,Cu-P-Cr-Ni-Mo热轧双相耐候钢的抗拉强度和屈服强度分别提高了21.6%~37.2%,6%~13.8%,屈强比降低了12.7%~19.7%;Cu-P-Cr-Ni-Mo热轧双相耐候钢的耐腐蚀性能优于09CuPCrNi耐候钢;Cu-P-Cr-Ni-Mo热轧双相耐候钢焊件的抗拉强度比其母材的抗拉强度降低了大约7%,但比常规热轧的Cu-P-Cr-Ni-Mo耐候钢板强度提高了16%。
