Microstructure and mechanical properties of weld of 15Cr2Mo1 heat resistant steel repaired by NiCrFe filler alloy

Aiming at the problem that surface cracks occur in the service of 15Cr2Mo1 heat resistant steel welds, NiCrFe alloy which was similar to the usage scenarios of this steel was employed to repair welds with different groove depths simulating crack depths. The feasibility of repair process was verified...
