Chemical Additions to Reduce Hot Tearing in the Cast House
2012Hot tear susceptibility in VDC casting is strongly affected by the chemical additions of alloys, hardeners and grain refiners. This paper assesses a few different approaches to reducing hot tearing in the cast house. Grain refinement is one commonly used approach, including dosing at cast start.

Hot tearing evaluation for aluminium alloys
AIP Conference Proceedings, 2016Hot tearing during solidification of aluminium alloys castings can be a serious problem. This phenomenon is well known but still insufficiently investigated. Hot tearing occurs in form of irregular cracks in metal castings that develop during solidification and cooling.

Hot tears in grey iron castings
2015In general, one of the main casting defects due to residual stresses are cracks (tears). Cracks may be defined as a material separation, which is caused by mechanical and dynamic overloads. There are cold and hot cracks, depending on the temperature range in which they occurred.

Hot tearing of aluminium - copper alloys
2003For 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 tearing is one of most severe casting defects and contributes to increased scrap rate and reduced productivity particularly in the VDC casting process. Extensive work has therefore been conducted to improve the understanding of the mechanisms at play.
