Hot tearing susceptibility of aluminum alloys using CRCM-Horizontal mold
Results in Physics, 2017 Hot tearing is one of the common defects in casting products. Hot tearing susceptibility (HTS) is evaluated using three casting temperatures: 710, 760 and 810 °C.

A Quest for a New Hot Tearing Criterion [PDF]
Metallurgical and Materials Transactions A, 2007 Hot tearing remains a major problem of casting technology despite decades-long efforts to develop working hot tearing criteria and to implement those into casting process computer simulation. Existing models allow one to calculate the stress-strain and temperature situation in a casting (ingot, billet) and to compare those with the chosen hot tearing ...

Bifilms and Hot Tearing of Al-Si Alloys
, 2016 Hot tearing is one of the most interesting defects that can be found during casting of aluminium alloys. The definition of this defects has some uncertainties such as “it does not always appear under apparently identical conditions” or “the defect is highly specific to certain alloys”.

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 (
