The effect of air-cooling heat treatments on the high strength, high toughness Fe/4Cr/0.3C/2Mn alloy has been investigated. Transmission electron microscopy revealed predominately dislocated lath martensite co-existing with lower bainitic ferrite laths when this alloy was air-cooled from a variety of austenitization temperatures. In addition, fine interlath films of retained austenite have been observed. The mechanical properties however, have been found to show a marked degradation in toughness as indicated by plane strain and impact toughness tests, and compared to quench and temper results. This loss of toughness has been attributed to the presence of undissolved carbides and secondary austenitic decomposition products.
