Influence of cerium addition on the resistance to oxidation of AM50 alloy prepared by rapid solidification

Influence of Al and Y on the ignition and flammability of Mg alloys

“…Li et al [12] and Huang et al [13] found that the ignition temperature of AZ91 increased by 60-80°C, attributed to CeO formation within the porous surface MgO, thereby inhibiting further oxidation. Similarly, Lin et al [14,15] found that increasing concentrations of Ce (0-1 wt%) increased the ignition temperature of rapidly solidified AM50 by up to 60°C. In contrast, there was an increase in ignition temperature at low Ce concentrations (0.15 wt%) for normally solidified AM50 and AZ91, but the ignition temperature decreased on increasing the Ce concentration to 1 wt%.…”

“…Al 11 Ce 3 formation was suppressed in rapidly solidified specimens. Similarly, the ignition temperature of AZ91D powders increased [14,15] for Y concentrations up to 0.2 wt%, followed by a decrease. This was similarly explained in terms of Al 2 Y formation that depleted the Y available for protective Y-oxide formation.…”

Effect of Zn addition on the oxidation property of Mg-Y alloy at high temperatures

“…Thus, with the increase of Zn content (from 0 to 3.5 wt%), the second phase changed from Mg-Y binary phase to Mg-Y-Zn ternary phases in Mg-3Y-xZn alloy. The properties of second phases are likely to make a difference to the high temperature oxidation resistance of the alloys [21].…”

Thermal fatigue behavior of Mg–9Al–Zn alloy with biomimetic strengthening units processed by laser surface remelting

“…The Nd:YAG (neodymium: yttrium-aluminum-garnet) pulsed laser was used to treat the sample surface in the protective atmosphere of high-purity argon. Previous studies showed that Mg is very susceptible to elevated temperature corrosion and oxidation [19,20]; therefore, samples should have been well protected using inert atmosphere. The wavelength of applied laser beam was 1.06 μm.…”
