摘要
In the present invention, being disclosed a kind of magnesium-based casting alloy salt fog has good corrosion-resistant and improved creep resistance, tensile yield strength and bolt-holding, especially at elevated temperatures degC at least 150. Alloy of the invention includes the aluminium of 2 to 9 weight percent, 0.The strontium of 1 to 7 weight ratio, remaining is magnesium, in addition to impurity is usually in magnesium alloy. A kind of manufacture oxidation-resistant alloy melt, the method prepared with alloy melt by this method are also provided. Method of the invention includes: the mixture of inert gas is selected from carbon dioxide and sulfur fluoride gas, nitrogen and sulfur dioxide gas under the atmosphere of melted alloy metal, and combinations thereof. Further provided is that a kind of magnesium-based alloy cast for preparing is from above-mentioned alloy melt, and the method for the alloy-steel casting prepared by this method.
