The Low-Cycle Fatigue Behavior of a High-Strength Low-Alloy Steel Subjected to Tempforming [PDF]
MaterialsThe developed microstructures and their deformation behavior were studied in a high-strength low-alloy steel subjected to tempforming, i.e., tempering followed by large-strain rolling at temperatures of 823 K or 923 K. Tempforming has been recently proposed as an advanced treatment for low-alloy steels in order to substantially increase their impact ...

Strengthening Mechanisms in a Medium-Carbon Steel Subjected to Thermo-Mechanical Processing [PDF]
Applied Sciences, 2023 Strengthening mechanisms were examined in a Fe-0.43C-1.60Si-0.01Mn-1.1Cr-0.95Mo-0.08V-0.05Nb steel exhibiting a yield strength (YS) of 1310 MPa after tempering and 1550 MPa after tempforming. The dislocation strengthening gave a major contribution to the

Effect of tempforming on strength and toughness of medium-carbon low-alloy steel [PDF]
, 2022 The effect of tempforming on the strength and fracture toughness of 0.4%C-2%Si-1%Cr-1%Mo-VNb steel was examined. Plate rolling followed by tempering at the same temperature of 600°C increases yield stress by 25% and the Charpy V-notch impact energy by a ...
