A New Criterion for Prediction of Hot Tearing Susceptibility of Cast Alloys

Metallurgical and Materials Transactions A, 2014
A 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-

Prediction of Hot Tearing Susceptibility for Mg-Zn-(Al) Alloys

Advanced Materials Research, 2012
It 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 ...

Observation and Prediction of the Hot Tear Susceptibility of Ternary Al-Si-Mg Alloys

Metallurgical and Materials Transactions A, 2012
An investigation into the hot tear susceptibility of ternary Al-Si-Mg alloys has been made using direct crack observation, measurement of load response, and predictions made by a modified Rappaz-Drezet-Gremaud (RDG) hot tearing model. A peak in both the hot tear susceptibility and the load at solidus occurred at approximately 0.2Si and 0.15Mg, and then

Influence of yttrium additions on the hot tearing susceptibility of magnesium–zinc alloys

Materials Science and Engineering: A, 2010
Abstract 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, 2010
The 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.

Effect of SiC particles content on the hot tearing susceptibility of SiC/Al5Cu composites

Ceramics International, 2020
Abstract 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 Tearing Susceptibility and Solidification Behavior of Mg-xGd-(4-x)Y-2Ni-0.5Zr Alloys

Integrated Ferroelectrics
The hot tearing susceptibility (HTS) of Mg-xGd-(4-x)Y-2Ni-0.5Zr (x = 0, 1, 2, 3, 4, wt%) alloys was evaluated using a T-shape mold method. When the Gd element increased and the Y element decreased, the HTS of the alloys decreases gradually. The Mg-4Y-2Ni-

Hot-Tear Susceptibility of Aluminum Wrought Alloys and the Effect of Grain Refining

Metallurgical and Materials Transactions A, 2007
Hot-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
