Modification of Constrained Rod Casting Mold for New Hot Tearing Measurement [PDF]
Archives of Metallurgy and Materials, 2018 Hot tearing severity was evaluated in this experiment by introducing a new apparatus called Constrained Rod Casting Modified Horizontal (CRCM-Horizontal). Six constraint bars with different lengths can produce hot tearing on the cast sample.

A new hot-tearing criterion [PDF]
Metallurgical and Materials Transactions A, 1999 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, it accounts for the tensile deformation of the solid skeleton perpendicular to the growing dendrites and for the induced interdendritic liquid feeding. This model introduces a critical deformation rate (
