Magnesium Yttrium Gadolinium (Mg-Y-Gd) Master Alloy

Product Information

Magnesium-yttrium-gadolinium master alloy is a kind of ternary alloy. Rare earth has a good purifying effect on magnesium alloy melt, and it has the functions of purifying hydrogen and removing oxidized inclusions. 

Magnesium-yttrium-gadolinium casting alloy is made by melting metal magnesium, Gadolinium, and metal yttrium. The common alloy ratio is 20-70% magnesium, and the ratio can also be customized. The magnesium-based master alloy has a uniform and stable composition, which can meet the requirements of magnesium alloy composition, microstructure regulation, and performance improvement. Static cast finished products are available in a variety of forms including full or cut waffle ingot and notch bar ingot. Magnesium Yttrium Gadolinium (Mg-Y-Gd) Master Alloy master alloys are also available in the shot, screened and sized to specification and in bagged shot.

Magnesium-gadolinium of the present invention-yittrium alloy has the following advantages:

1), the atomic size that adds Y element: Y and magnesium differs greatly, and can make the magnesium matrix dot matrix produce distortion, carries heavy alloyed homogenization temperature and Young's modulus, slow down diffusion and self-diffusion process, the speed of reduction climb of dislocation is strengthened matrix.

2), when Y addition in Mg surpasses 4.52 (massfraction), the MgO that generates during alloy high-temp and Y 2O 3Can effectively stop alloy to continue oxidation, and along with the rising of oxidizing temperature and the increase protective membrane of Y content obviously thicken.

3), add the Gd element: gadolinium has similar chemical property to yttrium, by distribution and the existence form of control Gd in alloy substrate, puies forward heavy alloyed mechanical property.

4), add the Mn element: Mn element and the rare earth element generation multiple compounds that can react, these violent rare earths have preferably thermotolerance, and being distributed in the alloy substrate of energy disperse can improve the mechanical property of alloy, resistance toheat particularly strengthens intensity and the heat resistance of alloy.

5), add the Ti element: avoid the alloy surface blackout, in order to obtain the relatively surface of light.

Magnesium-gadolinium of the present invention-yittrium alloy, good heat resistance, intensity is high, can be applicable on aerospace field and the automotive industry high-temperature-resistant structure spare.

Magnesium Yttrium Gadolinium Master Alloy Application

The addition of rare earth elements such as Y and Nd in the Mg-Gd binary alloy system can further promote the aging precipitation kinetics of the alloy and increase the strength.
