Effect of Cu on the Hot Tearing Susceptibility of Al–6Zn–2.5Mg–xCu Alloy
International Journal of Metalcasting, 2020Based on the modified Clyne–Davies model and the “T”-type hot tearing test system, the hot tearing susceptibility of Al–6Zn–2.5Mg–xCu (x = 0, 1, 2, 3 wt%) alloy was predicted and verified. The results showed that the hot tearing susceptibility first decreased and then increased with the increase in the content of Cu, and the smallest was at the content

A New Criterion for Prediction of Hot Tearing Susceptibility of Cast Alloys
Metallurgical and Materials Transactions A, 2014A new criterion for prediction of hot tearing susceptibility of cast alloys is suggested which takes into account the effects of both important mechanical and metallurgical factors and is believed to be less sensitive to the presence of volume defects such as bifilms and inclusions. The criterion was validated by studying the hot tearing tendency of Al-

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 ...

Prediction of Hot Tearing Susceptibility for Mg-Zn-(Al) Alloys
Advanced Materials Research, 2012It is importance to be able to predict the hot tearing tendency for multicomponent magnesium alloys. Hot tearing is one of the most common and serious defects that occurs during the solidification of commercial magnesium alloys. Clyne and Davies correlated the susceptibility-composition relationship in binary systems based on the concept of the ...

Influence of yttrium additions on the hot tearing susceptibility of magnesium–zinc alloys
Materials Science and Engineering: A, 2010Abstract The influence of Y additions on the hot tearing behaviour of Mg–Zn alloys was investigated in this study. In permanent mould castings and in direct chill cast ingots, alloying of a few wt.% Y results in a significant reduction of hot tearing susceptibility.

Hot-Tearing Susceptibility of Ternary Mg-Al-Sr Alloy Castings
Metallurgical and Materials Transactions A, 2010The susceptibility of Mg-Al-Sr alloys to hot tearing during permanent mold casting was investigated using constrained rod casting (CRC) in a steel mold. The alloys included Mg-xAl-1.5Sr and Mg-xAl-3Sr, where x = 4, 6, or 8 wt pct. The hot-tearing susceptibility (HTS) was determined based on the widths and locations of the cracks in the rods.

Improvement of yttrium on the hot tearing susceptibility of 6TiB2/Al-5Cu composite
Journal of Rare Earths, 2015Abstract To improve the severe hot tearing susceptibility of TiB 2 reinforced Al-5Cu matrix composites, the present research investigated the influence of Y on the hot tearing susceptibility of 6TiB 2 /Al-5Cu composite. For the composite added with Y, the solidification temperature range was shortened, which was caused by the novel τ 1 -Al 8 Cu 4 Y ...

Effect of SiC particles content on the hot tearing susceptibility of SiC/Al5Cu composites
Ceramics International, 2020Abstract The aim of present research was to investigate the hot tearing susceptibility (HTS) of SiC reinforced Al5Cu matrix composites. The HTS value of Al5Cu was 19.3, and the HTS values were 6.14, 16.05 and 44.98, corresponding to 0.5SiC/Al5Cu, 1SiC/Al5Cu and 2SiC/Al5Cu, respectively.

Hot-Tear Susceptibility of Aluminum Wrought Alloys and the Effect of Grain Refining
Metallurgical and Materials Transactions A, 2007Hot-tear resistance of aluminum wrought alloys AA1050, AA3104, and AA5182 has been determined via constrained-rod casting and two quantitative indices. Hot-tear susceptibility ranking was observed to be AA1050

Hot Tear Susceptibility of Al-Mg-Si-Fe Alloys with Varying Iron Contents
Metallurgical and Materials Transactions A, 2012Hot tear susceptibility in cast Al-0.52Si-0.34Mg-xFe 6060 aluminum alloys was investigated using a hot tearing test apparatus to simulate hot tearing in DC casting. The test apparatus has two cast bars, one that is used to measure the load response and one which is fixed at both ends to restrain thermal contraction so that hot tearing can be observed ...
