It was found that the nucleation undercooling of the α-Mg phase increased from 2.3 to 6.3 °C. The average α-Mg grain size increased from 44 to 71 μm, but then decreased to 46 μm. The morphology of the eutectic compound transformed from a continuous network into a discontinuous state and then subsequently into an island-like block. The volume fraction of β-Mg24RE5 phase increased and its morphology transformed from particle into rod-like. The increase in pouring temperature increased the solute concentration. YS increased from 138 to 151 MPa, and UTS increased from 186 to 197 MPa. The alloy poured at 750 °C had optimal combining strength and ductility. The fracture surface mode transformed from quasi-cleavage crack into transgranular fracture, all plus the dimple-like fracture, with the micro-porosity and the re-oxidation inclusion as major defects. The average α-Mg grain size played a main role in the YS of sand-cast Mg−10Gd−3Y−0.4Zr alloy, besides other factors, i.e. micro-porosity, morphology of eutectic compounds, re-oxidation inclusion and solute concentration.}, number={2}, journal={TRANSACTIONS OF NONFERROUS METALS SOCIETY OF CHINA}, author={Pang, Song and Wu, Guo-hua and Liu, Wen-cai and Zhang, Liang and Zhang, Yang and Conrad, Hans and Ding, Wen-jiang}, year={2015}, month={Feb}, pages={363–374} }

With the increase in cooling rate, the nucleation temperature (Tα,N) increases from 634.8 °C to 636.3 °C, the minimum temperature (Tα,Min) decreases from 631.9 °C to 630.7 °C, the nucleation undercooling (ΔTN) increases from 2.9 °C to 5.6 °C, the beginning temperature of the eutectic reaction (Teut,N) increases, the time of the eutectic reaction shortens, solidus temperature decreases from 546.0 °C to 541.4 °C, and solidification temperature range (ΔTS) increases by 6.1 °C. The increased nucleation rate () is supposed to be the main reason for the increased ΔTN. Increased value (Teut,N–Teut,G) and shortened time of the eutectic reaction cause the change in the volume fraction and morphology of the second phase.}, number={11}, journal={TRANSACTIONS OF NONFERROUS METALS SOCIETY OF CHINA}, author={Pang, Song and Wu, Guo-hua and Liu, Wen-cai and Zhang, Liang and Zhang, Yang and Conrad, Hans and Ding, Wen-jiang}, year={2014}, month={Nov}, pages={3413–3420} }
