Hot Tearing in Cast Aluminum Alloys

Materials Science Forum, 2011
MPI and CANMET, both members of the Light Metal Alliance, launched a research project to study hot tearing in aluminum alloys. In this project, a reliable test method to quantitatively evaluate hot tearing was developed, and the processing variables affecting hot tearing tendency were also investigated.

Hot-tearing in Aluminium Copper Alloys

Cast Metals, 1988
An experimental technique has been developed to investigate hot tearing. In this technique either the load or strain built up during casting could be measured as a function of the mould wall temper...

A Review on Hot Tearing of Steels

International Journal of Metalcasting, 2021
Hot tearing is a common solidification defect in both continuous cast steels and foundry shaped castings, which has a significant impact on the quality of the final products. It is a complex phenomenon that involves both the thermal and mechanical conditions and chemical element segregation that evolves during casting process.

Castability—Fluidity and Hot Tearing

2008
AbstractCastability of alloys is a measure of their ability to be cast to a given shape with a given process without the formation of casting defects. This article describes the factors that limit fluidity as well as experimental methods for measuring fluidity of various alloys.

Hot Tearing in Aluminium — Copper Alloys

2016
For many aluminium alloys, hot tearing susceptibility follows a lambda curve relationship when hot tearing severity is plotted as a function of solute content. In the past, there has been some difficulty quantifying hot tearing. Traditional methods rely upon measuring electrical resistivity or the number and/or length of cracks in tests such as the ...

Hot tear susceptibility of aluminium–silicon binary alloys

International Journal of Cast Metals Research, 2010
AbstractHot tear susceptibility (HTS) of Al–Si alloys in the 0–5–3·0 wt-%Si has been determined using a constrained rod casting test and a quantitative index. Hot tear susceptibility was seen to decrease with increasing silicon content. Hot tear severity varied directly with solidification shrinkageβ, the non-equilibrium freezing range ΔT′, dendrite ...

A quantitative hot tearing criterion for aluminum alloys

Engineering Research Express
In this study, a new hot tearing criterion was proposed to quantitatively predict open and segregated hot tears in aluminum alloys. In the suggested model, the displacement of grains at a grain boundary near the solidus temperature was considered as the ...

Assessment of Segregation in Hot Tear Cracks

steel research international, 2008
In solidified slabs different types of segregations such as crystal segregation (micro segregation), centre segregation (macro segregation) and hot tear segregation (HTS) may occur. The present paper examines the segregation behaviour of different elements in hot tear cracks depending on the carbon content.

The hot-tearing of copper alloys

1965
A test and a rating method have been developed to assess the hot-tearing susceptibility of cast copper alloys. Thirteen alloys were rated, and, while the limitations of individual hot-tear tests are well known, it is considered that such a rating should serve as a general guide to enable foundrymen to select alloys with the best hot-tear resistance ...

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”.
