Understanding the roles of interdendritic bridging on hot tearing formation during alloy solidification

open access: yesJournal of Materials Research and Technology, 2023
Dendritic bridging plays a key role in hot tearing formation and crack propagation, but it has yet to be clearly understood. This article describes the formation process of interdendritic bridging and its effect on the propagation of hot tearing.

Grain Refinement Effect on the Hot-Tearing Resistance of Higher-Temperature Al–Cu–Mn–Zr Alloys

open access: yesMetals, 2020
The hot-tearing resistance of Al-Cu-Mn-Zr (ACMZ) alloys was investigated as a steptoward introducing these new cast alloys for severe duty, higher-temperature applications, such ascylinder heads for down-sized, turbocharged automotive engines.

Integrated Approach for Prediction of Hot Tearing [PDF]

open access: yesMetallurgical and Materials Transactions A, 2009
Shrinkage, imposed strain rate, and (lack of) feeding are considered the main factors that determine cavity formation or the formation of hot tears. A hot-tearing model is proposed that will combine a macroscopic description of the casting process and a microscopic model.

Effects of Zn content on Hot Tearing Susceptibility of Mg–7Gd–5Y–0.5Zr Alloy

open access: yesMetals, 2020
Mg−7Gd−5Y−0.5Zr alloy has excellent mechanical properties but poor hot tearing resistance. The latter makes it difficult to cast billets, which limits the size of subsequently processed parts.

Hot tearing susceptibility of Mg-5Nd-xZn alloys

open access: yes, 2016
Magnesium-neodynium-zinc (Mg-Nd-Zn) alloys are promising candidates as creep resistant alloys. Further, Nd is a rare earth (RE) addition with lower solid solubility and a relatively lower cost.

Meso-scale modelling of semi-solid deformation in aluminum foundry alloys: Effects of feeding and microstructure on hot tearing susceptibility [PDF]

open access: yes, 2020
In the context of hot tearing susceptibility, the semi-solid constitutive behaviour of two commercially important foundry aluminum alloys at high solid fraction has been simulated. The numerical methodology combines solid mechanics, computational fluid

Microstructures and mechanical properties of zirconium-containing 7×××aluminum alloy prepared by selective laser melting

open access: yesCailiao gongcheng, 2021
The preparation of 7×××series aluminum alloy by selective laser melting technology (SLM) is hindered by hot tearing. Novel ZrH2 modified 7075 composite powders were prepared by the low-energy ball milling technology.
