Note: Influence of allowing elements, here chromium, on the transformation of subcooled
austenite described according to CCT diagrams of (a) a 1040 steel with about 0.15 wt% Cr (German
grade Ck45) and (b) a 5140 steel with about 1 wt% Cr (German grade 41Cr4), and (c) a steel with about 1.5 wt% Cr and 0.7 wt% Mo (German grade
45CrMoV67).
