  b.) 0.30% C, 0.10% Mn, 1.42% Si, 1.03% Cr, 0.22% Mo, 3.48% Ni, 0.040% Al
  c.) 0.32% C, 0.61% Mn, 0.30% Si, 1.74% Cr, 0.25% Mo, 3.58% Ni, 1.25% Al
  Note: CCT diagrams for samples with an austenite grain size in the range 40–60 µm and austenitisation
  temperature of 1000^oC. (a) Alloy 1. (b) Alloy 2. (c) Alloy 3. The terms alpha, alpha(b) and alpha' refer to
  allotriomorphic ferrite, bainite and martensite respectively. 1. The samples were heated at 5^oCs-1 up to
  1000^oC and then immediately cooled without holding at the maximum temperature. The cooling rates
  used were constant and in the range 0.1–10^oCs-1. The measured austenite grain size was for all the
  samples, in the range 40–60 µm.
