text: In recent publications, prof. Sindo Kou has proposed an approach to evaluate susceptibility to solidification cracking; this approach is based on a similar approach where a quantity, , which has the dimensions of a temperature is proposed as an index of the cracking susceptibility. Again one could exploit Scheil based solidification curves to link this index to the slope of the (Scheil) solidification curve:
  ∂T/(∂(fS)^1/2)=
  ∂T/(∂(fS)*(∂(fS)^1/2)/∂(fS))=
  (1/2)∂T/∂(fS)*(fS)^1/2=
