Deformation and fracture behaviour of a dual-phase Cr-V steel

1983 Transactions of the Iron and Steel Institute of Japan  
Synopsis Dual phase structure in an HSLA steel containing 1 % Cr and 0.2 % V was produced by cooling from austenite field to the (a+r) region, then quenching in iced brine. The quenched steels were tempered at 700 °C. Linear equations were proposed to express the effect of martensite volume fraction and tensile strength on uniform elongation, products of tensile strength and uniform or total elongation. Cleavage and/or void coalescence was the operating mode of fracture for quenched steels,
