Effect of thermal cycle of welding and reheating on structural-constitutional changes of low-alloyed <i>Cr</i>-<i>Ni</i>-<i>Mo</i>-<i>V</i> steel

Effect of thermal cycle of welding and reheating on structural-constitutional changes of low-alloyed <i>Cr</i>-<i>Ni</i>-<i>Mo</i>-<i>V</i> steel

The work objective is to study the impact of the thermal welding cycle (TWC) and reheating on the metal embrittlement kinetics of the heat affected zone (HAZ) of 15H2NMFA-VRV steel joint welds. The problem of the technological strength improvement of the welded joints of the nuclear power plant equi...
