Effect of Y content on hot tearing susceptibility of MgZn₉Y_xZr_0.5 alloys

Cailiao gongcheng, 2019
Based on the Clyne-Davies model,the hot tearing susceptibility(CSC)of MgZn9YxZr0.5(x=1,2,4,6,mass fraction/%) was predicted.The microstructure and morphology of hot tearing regions of the alloys were observed by X-ray diffraction (XRD) and scanning ...

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 ...

The influence of hydrogen on the hot tearing susceptibility of aluminium-silicon alloys

, 2004
An automotive company has recently adopted procedures to control the melt hydrogen content of their cast aluminum air-intake manifolds. This arose because the hydrogen content showed a strong correlation with the incidents of hot tearing. Although the literature typically reports a negative impact of hydrogen on hot tearing it was clearly observed that
