“…Recently, Rokhlin et al [1] and Anthony et al [2][3] have developed Mg-Gd-Y alloys which exhibit higher specific strength at both room and elevated temperature and good creep resistance than conventional Al and Mg alloys, including WE54, whose high temperature strength was the top of existing commercial magnesium alloys. Furthermore, it was reported that the addition of Ca is an effective way to improve the elevated temperature properties, creep resistance and corrosion resistance of Mg-Al alloys [4][5][6]. However, few researches concern the effect of Ca additions on magnesium-HRE alloys.…”

The microstructure, mechanical properties, creep and corrosion resistance of Mg-Gd-Y-Zr(-Ca) alloys were studied. Small additions of 0.4-0.6 wt% Ca to Mg-(9-10)Gd-3Y-0.4Zr(wt.%) alloys led to a slight improvement in creep resistance and a remarkable increase in corrosion resistance, but an obvious decrease in elongation to fracture. UTS and TYS of the Mg-Gd-Y-Zr(-Ca) alloys are obviously higher than those of WE54, especially in the temperature range from room temperature to 200 oC. TEM images and corresponding energy dispersive x-ray spectra showed that the Ca element primarily segregated to the grain boundaries and existed in the cuboid-shaped particles with a trace concentration, and the small addition of Ca had no obvious effect on the orientation, morphology, and distribution of β′ phase, which is responsible for the peak hardness in Mg-Gd-Y-Zr alloys.

“…However, the commonly used Mg alloys such as AZ91 alloy and AM60 alloy are unsuitable for use above 150-200˚C [3] . It was found that Ca addition greatly improves the elevated temperature properties of as-cast Mg-Al alloys because of the formation of the heat-resistant Al 2 Ca phase, which has a relatively high melting point [4] . Alloying with Ca is becoming more common in the development of cheap creep-resistant alloys, essentially replacing Mg 17 Al 12 with Al 2 Ca [4][5] .…”

As-cast AM50 magnesium alloys containing 0, 1, 2 wt. %Ca were extruded firstly at 673K with an extrusion ratio 1:9, and then at 573K with an extrusion ratio 1:16. Microstructure, tensile properties and fractographs were investigated. With Ca content increasing, the amount of Al2Ca increases and that of Mg17Al12 decreases. Ca refines the microstructure of as-cast and extruded AM50 magnesium alloys. For the extruded magnesium alloys, tensile strength improved and elongation decreased at room temperature, while tensile strength was reduced a little and elongation reduced at the temperature of 100°C, 150°C and 200°C with increasing Ca content. The tearing face increases with Ca content increasing for the tensile fractographs.
