  • Effect of tempering temperatures on the mechanical properties and microstructures of structural steel Micral 690 = Vpliv temperature popuščanja na mehanske lastnosti in mikrostrukturo konstrukcijskega jekla Micral 690
    Skobir Balantič, Danijela Anica ...
    Heat treatment of the structural steel consists of quenching in water and tempering. To study the effect of tempering temperature on the microstructure and mechanical properties, the as-quenched ... steel was tempered at different temperatures (from 250 °C to 670 °C). Tensile strength decreases with increasing tempering temperature. The impact toughness is highest in the tempering temperature range of 550-600 °C. The microstructure of the as-quenched steel consists of martensite and some bainite. With increasing the tempering temperature tempering effects appear and the martensite microstructure starts disappearing.
