Research was conducted to determine if alloying magnesium with sparingly soluble V, cb, ta, cr, mo, and w would inhibit burning of molten magnesium and corrosion resistance of solid magnesium. When molten magnesium was heated for 1 hr (argon) in contact with the metals, solubilities ranged from <0.0010 wt-pct for mo, ta, cb, or w, up to 0.0028 pct for V, and 0.0129 pct for cr. Heating under pressure at 1,000 deg c resulted in 0.0544 pct soluble cr; at 1,400 deg. C, 0.0017 pct cb was soluble. Mg-cr and mg-w alloys exhibited slightly improved burning resistance. All alloys had diminished corrosion resistance in 3-pct nacl solution.
