A review on hot tearing of magnesium alloys

open access: yesJournal of Magnesium and Alloys, 2016
Hot tearing is often a major casting defect in magnesium alloys and has a significant impact on the quality of their casting products. Hot tearing of magnesium alloys is a complex solidification phenomenon which is still not fully understood, it is of ...

Hot tearing behavior of NZ30K Mg alloy under progressive solidification [PDF]

open access: yesChina Foundry, 2021
Progressive solidification is usually considered an effective strategy to reduce the hot tearing susceptibility of a cast component. In this study, special constrained plate castings with progressive changes in cross-section were designed, which enabled ...

Modification of Constrained Rod Casting Mold for New Hot Tearing Measurement [PDF]

open access: yesArchives 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.

Effects of Fe, Si, Cu, and TiB2 Grain Refiner Amounts on the Hot Tearing Susceptibility of 5083, 6061, and 7075 Aluminum Ingots

open access: yesMetals, 2023
Aluminum alloys 5083, 6061, and 7075 are prone to hot tearing under direct-chill casting conditions; the defects that form during solidification of those alloys are highly sensitive to variation in the alloying elements, with these elements commonly ...

Influence of a low-frequency alternating magnetic field on hot tearing susceptibility of EV31 magnesium alloy [PDF]

open access: yesChina Foundry, 2021
The effect of a low-frequency alternating magnetic field (AMF, 0 A 0 Hz, 5 A 10 Hz, 10 A 10 Hz, 15 A 10 Hz) on the hot tearing susceptibility (HTS) of a magnesium alloy (EV31) was systematically studied using a combination of experiment and numerical ...

A new hot-tearing criterion [PDF]

open access: yesMetallurgical 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 (
