Hot-tearing susceptibility of Al–Zn alloys
Russian Metallurgy (Metally), 2017The modern concepts of the causes of hot tearing are considered and the influence of the solid fraction growth rate of an alloy is studied. The hot-tearing susceptibility (HTS) of binary Al–(5–73) wt % Zn alloys is investigated using backbone tests. The HTS is found to be maximal at ~25 wt % Zn.

Hot Tearing Susceptibility of Mg-Ca Binary Alloys
Metallurgical and Materials Transactions A, 2015Hot tearing is known as one of the most critical solidification defects commonly encountered during casting practice. As most Mg alloys are initially prepared by casting, ingots must have superior quality with no casting defects for the further processing.

Estimation of Susceptibility to Hot Tearing in Solidifying Casting
2012Hot tearing, also called hot cracking, is a serious defect that appears during the solidification of an alloy. Due to the low recurrence of the phenomena occurring during alloy solidification, such as the evolution of grained structure or stress redistributions, the casting’s susceptibility to hot tearing can be estimated only in an approximate way ...

Effect of Y on the hot tearing susceptibility of 3Y2O3/Al5Cu composite
Journal of Alloys and Compounds, 2020Abstract Hot tearing susceptibility (HTS) refers to the casting defect that existed owing to the appreciable shrinkage at the final stage of solidification. Present research studied the effect of Y on the HTS of 3Y2O3/Al5Cu composite. After 0.3%, 1% and 2% Y (in wt.%) added, the HTS value of 3Y2O3/Al5Cu composite decreased by 2.1%, 39.5% and 61.9 ...

Hot Tearing Susceptibility of Magnesium–Gadolinium Binary Alloys
Transactions of the Indian Institute of Metals, 2012Hot tearing susceptibility of Mg–Gd alloys are investigated using instrumented constrained rod casting (CRC) apparatus, and found that the susceptibility increases with increase in Gd content, and reaches a maximum at 2 % after which it decreases to a minimum with 10 % Gd.

The research of casting properties especially the fluidity and hot tearing susceptibility is crucial for cast aluminum alloys. The fluidity and hot tearing susceptibility of two aluminum alloys were studied by three different methods (steel mold cast, thermal analysis and thermodynamic calculation), and the results were discussed in detail.

Hot Tearing Susceptibility of Mg-5Nd-xZn Alloys
2016Magnesium-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. Hence, the use of such alloys may result in a feasible and cost effective alternative for enhancing Mg alloy use in high temperature applications. Nevertheless,

Failure Analysis and Hot Tearing Susceptibility of Stainless Steel CF3M
International Journal of Metalcasting, 2018Hot tear formation has been witnessed during the solidification of the ferrous alloy by pulling the columnar dendrites in the transverse direction. The hot tearing susceptibility of an alloy is influenced by solidification rate, microstructure and the stress/strain conditions. It is valuable to predict the occurrence of tearing in a casting.

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.

A Novel Approach to Assessing the Hot Tearing Susceptibility of Aluminium Alloys
Materials Science Forum, 2000Previous work has shown that hot tearing is the result of differential contraction between the solid and liquid phases during the solidification of the ingot. Most of these studies have been on hot tearing problems in the bulk metal. However, it remains to be demonstrated how the shell region affects the occurrence of hot tearing during solidification ...
