A New Hot-Tearing Criterion
TL;DR: In this article, a new criterion for the appearance of hot tears in metallic alloys is proposed, based upon a mass balance performed over the liquid and solid phases, which accounts for the tensile deformation of the solid skeleton perpendicular to the growing dendrites and for the induced interdendritic liquid feeding.

A criterion for cracking during solidification
TL;DR: In this article, an index for the susceptibility of an alloy to cracking during solidification was also proposed, that is, |dT/d(fS1/2)| near (fS) 1/2 ǫ = 1, where T is temperature and fS the fraction solid in the semisolid.
