Hydrogen embrittlement of the coarse grain heat affected Jun 24, 2020 · The coarse grain heat affected zone (CG-HAZ) of welds produced in a quenched and tempered 42CrMo4 steel was simulated by means of a laboratory heat treatment consisting in austenitizing at 1200 °C for 20 min, oil quenching and finally applying a post weld heat treatment at 700 °C for 2 h (similar to the tempering treatment previously applied to the base steel).
In heat treatment a fundamental distinction can be made between the hardening and tempering processes. Hardening comprises the heating and quenching of a workpiece in order to increase its hardness and strength. 42CrMo4 1.7225 0.38 0.45 0.40 0.60
The Effect of Temperature Distribution During Laser Heat 1 day ago · A gas-nitrided layer was produced on the toughened 42CrMo4 low-alloy steel using the changeable nitriding potential in order to limit the thickness of a brittle zone. The microstructure consisted of the compound + ( + ) zone and diffusion zone (nitric sorbite with precipitates). Such a layer was subjected to laser heat treatment with or without remelting.
