Abstract

The study investigates ignition and oxidation behavior of Mg-3Nd-3Gd-0.2Zr-0.2Zn (wt.%) (EV33 alloy) in air and varying pressure. EV33 exhibits easy ignition in air but not under specific pressure conditions. Surface microstructure evolution and detailed discussion of ignition mechanisms using oxidation mechanism and residual stress of oxide film are presented. Findings suggest a correlation between alloy ignition and oxide film rupture. Surface oxidation film rupture is the direct cause of ignition in magnesium alloys, and this phenomenon has been observed and documented for the first time. The residual stresses calculated under atmospheric conditions and at pressures of 0.05 MPa, 0.1 MPa, and 0.15 MPa (with air as the pressure medium) are as follows: 0.282 GPa, 0.561 GPa, 2.271 GPa, and 5.242 GPa.
