Hot tearing susceptibility of aluminum alloys using CRCM-Horizontal mold
Results in Physics, 2017 Hot tearing is one of the common defects in casting products. Hot tearing susceptibility (HTS) is evaluated using three casting temperatures: 710, 760 and 810 °C.

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

Formation of Hot Tear Under Controlled Solidification Conditions [PDF]
Metallurgical and Materials Transactions A, 2014 Aluminum alloy 7050 is known for its superior mechanical properties, and thus finds its application in aerospace industry. Vertical direct-chill (DC) casting process is typically employed for producing such an alloy. Despite its advantages, AA7050 is considered as a “hard-to-cast” alloy because of its propensity to cold cracking.

Integrated Approach for Prediction of Hot Tearing [PDF]
Metallurgical 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.

Hot tearing susceptibility of binary Mg–Y alloy castings [PDF]
Materials & Design, 2013 Abstract The influence of Y content on the hot tearing susceptibility (HTS) of binary Mg–Y alloys has been predicted using thermodynamic calculations based on Clyne and Davies model. The calculated results are compared with experimental results determined using a constrained rod casting (CRC) apparatus with a load cell and data acquisition system ...
