Magnesium rare earth zirconium cast magnesium alloy
Introduction
Magnesium alloys are light metals with low densities, high specific strength and harsh operating environments. As non-ferrous metals, they are widely used in automotive, aircraft, aerospace and military fields due to their excellent mechanical properties and high corrosion resistance. Magnesium rare earth zirconium cast alloys are a recently developed new type of magnesium alloy, which has good mechanical properties and has been widely used in aerospace and automotive applications.
Definition
Magnesium rare earth zirconium cast alloys are a new type of magnesium alloys containing rare earth elements (REE) and Zirconium, which are cast from these materials. This type of alloy is specially designed to improve the mechanical properties, weldability, corrosion resistance and fatigue resistance of magnesium. The mechanical properties of these alloys are significantly improved over traditional magnesium alloys due to the addition of rare earth elements and Zirconium.
Background
In the 1950s, researchers began to develop and study magnesium alloys. However, due to the severe corrosion and poor physical properties of wrought magnesium alloys, their use was limited. In recent decades, as reinforced magnesium alloy technology has been developed and applied, magnesium rare earth zirconium cast alloys have become more and more popular in the automobile, aircraft, aerospace and other industries due to their good properties such as high strength, high corrosion resistance, high temperature bearing capability and good weldability.
Composition
The chemical composition of magnesium rare earth zirconium cast alloys consists of Magnesium (Mg), Rare Earth Elements (REE) and Zirconium (Zr). The common elements contained in these alloys are Magnesium, Manganese (Mn), Aluminum (Al), Zirconium (Zr), Rare Earth Elements (REE), and Copper (Cu). Depending on the grade and type, the content of each element may vary. For example, a typical composition of the alloy may have 4-6% Zirconium, 0.5-1.5% rare earth elements, 0.5-2.0% copper, 0.2-1.0% manganese, 1.0-1.5% aluminum, and the remaining magnesium. Other elements such as Iron, Silicon and Titanium may also be present in the alloy.
Manufacturing Process
Magnesium rare earth zirconium cast alloys are manufactured by melting a magnesium alloy containing REE and Zr in a holding furnace and then pouring the molten metal into a mould to form the desired shape. The alloy is then heat treated and cut to the desired size.
Properties
Magnesium rare earth zirconium cast alloys have good mechanical properties and weldability due to the addition of rare earth elements and Zr. These alloys are also highly resistant to corrosion and wear and have a high temperature bearing capacity. These alloys also have good castability, as well as good impact toughness and fatigue properties.
Applications
Magnesium rare earth zirconium cast alloys are widely used in the aviation, automobile, aerospace and military industries due to their good properties. These alloys are used for structural components and chassis components, such as connecting rods, suspension parts, wheel hubs and engine mounts.
Conclusion
Magnesium rare earth zirconium cast alloys are a new type of magnesium alloy developed for use in the automotive, aircraft, aerospace and military industries due to their excellent mechanical properties, good weldability, corrosion and wear resistance and high temperature bearing capacity. These alloys are also relatively easy to manufacture, which makes them ideal for mass production.
