Abstract
Structure and mechanical properties of two copper bearing high-strength low-alloy steels (HSLA)—one similar to HSLA 80 and the other to HSLA 100—are studied in different aging conditions. Elemental copper precipitates of nanometer size have been found to play an important role in the formation of different types of microstructures and in enhancing the strength and toughness of the alloys. Other alloying elements such as Ti, Nb, and V result in fine precipitates of carbides and nitrides, which improve the mechanical strength.
