Example Embodiment
[0024] Example 1
[0025] 46kg Mg-Gd-Y ternary master alloy smelting method, wherein the alloy composition (weight percentage) is 11.83% Gd, 6.48% Y, and the rest is Mg.
[0026] Step 1. Take the raw materials of 37.52kg Mg-10wt.%Y binary master alloy ingot and 10.34kg Mg-60wt.%Gd binary master alloy ingot; clean the surfaces of the two binary master alloys and pre-process them. Heat to 150°C;
[0027] Step 2: Turn on the smelting furnace. The smelting furnace adopts resistance smelting furnace equipment, and 37.52kg of Mg-10wt.%Y binary master alloy ingot is added to the smelting furnace and heated to melt; when the temperature rises to 400℃, it starts Pass the inert gas Ar gas to protect the melt from oxidation and combustion;
[0028] Step 3: When the Mg-Y binary master alloy is completely melted, raise the temperature to 730℃, add Mg-Gd binary master alloy; dilute the original Mg-Y alloy melt; clamp it with iron clamps The Mg-60wt.% Gd master alloy ingot is placed under the li...

[0031] Example 2
[0032] The smelting method of 68kg Mg-Gd-Y ternary master alloy, wherein the alloy composition (weight percentage) is 7.88% Gd, 5.25% Y, and the rest is Mg.
[0033] Step 1. Take raw materials of 60.4kg of Mg-7.5wt.%Y binary master alloy and 10.2kg of Mg-60wt.%Gd binary master alloy ingot; clean the surfaces of the two binary master alloys and preheat them To 250°C;
[0034] Step 2: Turn on the smelting furnace. The smelting furnace adopts resistance smelting furnace equipment, and the Mg-7.5wt.% Y binary master alloy ingot is added to the smelting furnace and heated to melt; when the temperature rises to 450 ℃, the smelting furnace starts Into Ar gas and SF 6 The mixed gas protects the melt from oxidation and combustion;
[0035] Step 3: When the alloy in the melting furnace is all melted, raise the temperature to 740°C, add Mg-60wt.% Gd binary master alloy ingot; dilute the original Mg-Y alloy melt; use iron clamps to clamp Hold the Mg-60wt.%Gd master alloy in...

[0038] Example 3
[0039] The smelting method of 69kg Mg-Gd-Y ternary master alloy, wherein the alloy composition (weight percentage) is 10.5% Gd, 3.5% Y, and the rest is Mg.
[0040]Step 1. Take raw materials of 60.5kg of Mg-5wt.%Y binary master alloy and 10.4kg of Mg-80wt.%Gd binary master alloy ingot; clean the surfaces of the two binary master alloys and preheat them to 350°C;
[0041] Step 2: Turn on the melting furnace, add Mg-5wt.% Y binary master alloy to the melting furnace, and heat up to melt; when the temperature rises to 500 ℃, start to pass CO 2 With SF 6 The mixed gas protects the melt from oxidation and combustion;
[0042] Step 3: After all the alloys in the melting furnace are melted, the temperature is increased to 750°C, and Mg-80wt.% Gd binary master alloy ingots are added to dilute the original Mg-Y alloy melt. Use iron clamps to fix the Mg-80wt.%Gd master alloy ingot and place it under the liquid surface of the melt, and slightly agitate the alloy ingot, whi...
