Effect of Laser Annealing on Hot-stretching Properties of 1Cr5Mo Steel Welded Joints

Effect of Laser Annealing on Hot-stretching Properties of 1Cr5Mo Steel Welded Joints

The 1Cr5Mo heat-resistant steel welded joint was annealed with CO<sub>2</sub> laser, the effect of temperature on hot-stretching properties of the samples before and after laser annealing was analyzed by using stretching tests. The grain changes, rupture modes and fracture morphologies b...
