Hot-tearing in Aluminium Copper Alloys
Cast Metals, 1988An 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...

International Journal of Cast Metals Research, 2014
In this work, a new criterion for estimating hot tear susceptibility called overall hot tearing susceptibility (OHTS) is proposed to determine hot tearing tendency in the mould region during continuous casting. The OHTS criterion takes into account the cooling rate, brittle temperature range, strain rate and thickness of the brittle region.

Hot Tearing in Cast Aluminum Alloys
Materials Science Forum, 2011MPI 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.

Determination of Strain during Hot Tearing by Image Correlation
Metallurgical and Materials Transactions A, 2007The evolution of strain and strain at the onset of localization resulting in a hot tear has been determined for alloys AA6111, AA3104, CA31218, and Al-0.5 wt pct Cu during solidification. A bar constrained at both ends was solidified with a window above the hot spot region to allow observation of hot tear formation and growth.

Hot tear susceptibility of aluminium–silicon binary alloys
International Journal of Cast Metals Research, 2010AbstractHot 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 ...

In situ observation of hot tearing formation in succinonitrile-acetone
Acta Materialia, 2001Abstract Hot tears have been induced during the solidification of a succinonitrile-acetone alloy by pulling the columnar dendrites in the transverse direction with a pulling stick. The opening of the mushy zone (hot tears) always occurred at grain boundaries.

Hot tearing in aluminium alloys [PDF]
, 2011 Hot tearing continues to be a major problem in both Direct Chill (DC) and shape casting of aluminium alloys. It can limit productivity and influence the viability of casting some alloy compositions. While the underlying cause of hot tearing is understood i.e.
