Effect of the thermal cycle in welding on the structure and phase composition of the heat-affected zone in maraging steel

Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    The increase of grain size during welding depends on the cooling rate and on the time the metal remains at temperatures above the α→γ transformation temperature.

  2. 2.

    Cooling from α→γ transformation temperatures at a low rate leads to an increase in the amount of retained austenite and some reduction of hardness in the heat-affected zone.
