Mg-Gd-Y-Zr alloy castings are widely used in the aerospace field owing to their high strength and excellent creep resistance.The castability of these alloys is also an important consideration for engineering application.Thus,the hot tearing susceptibilities(HTSs)of Mg-10Gd-1Y-1Zn-0.5Zr(VW91)...
Hot Tearing Behavior in Double Ternary Eutectic Alloy System: Mg-Ce-Al AlloysTERNARY alloysALLOYSHYPEREUTECTIC alloysEUTECTIC reactionsALUMINUM-zinc alloysThe hot tearing behaviors of double ternary eutectic alloy system, Mg-4Ce- x Al ( x =0 to 9wt pct) alloys, were evaluated by a CRC mold. ...
Mg–1Al, Mg–0.9Y, Mg–2Gd, Mg–1.5Zn, and Mg–0.5Ca binary alloys were chosen to clarify the hot tearing mechanism since they exhibited the highest hot tearing susceptibility (HTS) among each binary alloy systems. Hot tearing tests of these five binary magnesium alloys were carried out b...
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 掳C. Four aluminum alloys were obtained from the melting of two ingots and casted into constrained rod casting modified-horizontal (CRCM...
Mg-Zn alloys are widely used as wrought alloys such as ZM, ZK and ZE series. They are reportedly to be prone to hot tearing due to the presence of Zn. The present work first evaluates the hot tearing susceptibility (HTS) of binary Mg-Zn alloys using quantitative experimental methods and ...

According to the diagram, tearing easily occurrs at high temperature and high speed conditions. Micro-solid bridge was observed at tearing surface to indicate the localization of melting of soluble Al2CuMg and MgZn2 compounds because temperature increased by friction coupled with tension stress ...
Hot tearing susceptibilityHot tearing is often a major casting defect in magnesium alloys and has a significant impact on the quality of their casting products. Hot tearing of magnesium alloys is a complex solidification phenomenon which is still not fully understood, it is of great importance to ...

The results show that the hot tearing susceptibility (HTS) decreases with the increase in x . Especially when x ≥1.5wt%, and the HTS of Mg–Y–Ni alloys is even lower than that of Mg–Y–Zn alloys. The analysis of solidification microstructure evolution reveals that with the increase in...
