Tempforming in medium-carbon low-alloy steel
Journal of Alloys and Compounds, 2013 Abstract Deformation of tempered martensitic structure, i.e., tempforming using a caliber rolling at 500 °C was applied to a 0.4%C–2%Si–1%Cr–1%Mo steel to obtain ultrafine elongated grain structure with a strong 〈1 1 0〉//RD fiber deformation texture and then tensile and Charpy impact properties were investigated.

On the fatigue behavior of high-strength low-alloy steels after tempforming
International Journal of Materials ResearchHigh-strength low-alloy steels were tempered followed by warm rolling at the same temperature (tempforming). The strengthening by tempforming significantly improved the low-cycle fatigue resistance with total number of reversals to failure below about ...

Friction Stir Welding-Induced Microstructural Changes in Low-Alloy Steel Post-Tempforming
Steel Research InternationalA feasibility of friction stir welding for a high‐strength low‐alloy steel subjected to tempforming, that is, tempering followed by large‐strain warm rolling at tempering temperature, is presented. The martensite microstructure tempered at 873 K for 1 h and then subjected to warm rolling to total strain of 1.5 is characterized by a lamellar‐type ...

Tempforming Strengthening of a Low-Alloy Steel [PDF]
Materials, 2022 Low-alloy structural steels subjected to quenching and tempering to achieve high strength possess a common drawback associated with low-impact toughness at low temperatures. An additional warm rolling, i.e., tempforming, is a promising approach to strengthen the rolled semi-products along with increasing their impact toughness.

Effect of Tempforming on Strength and Toughness of Medium-Carbon Low-Alloy Steel [PDF]
Materials, 2023 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 factor of ~10.
