PROBLEM TO BE SOLVED: To obtain a formed product excellent in room temp. and high temp. strength by using a specific composition of magnesium alloy and executing injection forming or semimelting forming. ;SOLUTION: This alloy has composition composed, by wt.%, of 2-10% aluminum, 1.0-10% calcium and the balance magnesium with inevitable impurities. Further, ≤2% at least one kind of element selected from the group of zinc, manganese, zirconium and silicon and/or ≤4% rare earth metals are added, at need. This alloy is formed into metallic grain or pellet and the injection forming is executed at the liquidus temp. or lower of the alloy or the semimelting forming is executed at the liquidus temp. or lower of mixture of the solid phase and the liquid phase. This formed product shows 200MPa 473K tensile strength and 14% elongation percentage, and further, shows 0.1244% strain at the initial stage, and ≃0%h min. creep velocity in the condition of 50MPa test load in the tensile creep test at 125°C.;COPYRIGHT: (C)1997,JPO
