Tempforming Strengthening of a Low-Alloy Steel. [PDF]
Materials (Basel), 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.
