Abstract

The invention discloses a heatproof magnesium alloy, which belongs to the magnesium alloy field. The magnesium alloy is composed of Mg, Zn, Zr, rare earth, Nb and Al, and comprises the following components by weight: 0.2-9% of Zn, 0.1-2% of Zr, 0.0002-16% of rare earth, 0.0002-4% of Nb, 0.001-1.49% of Al and the balance of Mg. The rare earth and an Nb element are added in the magnesium alloy, and a structure of a beta phase is changed; the Zr can strongly refine the crystal grain, and is reacted with certain impurity element (such as Si) in an alloy liquid and deposited, and the alloy liquid is purified. The combined effect of the elements enhances the high temperature resistance performance of the magnesium alloy, the heatproof magnesium alloy has excellent mechanical property and machinery processability, and good fluidity and die casting performance, and is suitable for casting the heatproof magnesium alloy and die casting of the heatproof magnesium alloy.

Description

technical field [0001] The invention relates to a magnesium alloy, in particular to a high-performance heat-resistant magnesium alloy suitable for casting. Background technique [0002] With the development of science and technology, vehicles represented by automobiles need to further develop new products with higher fuel efficiency by reducing the weight of the body. In the automobile manufacturing industry, magnesium alloy, as a new type of lightweight metal material, is used by automobile manufacturers to replace traditional cast iron in order to achieve the purpose of reducing the weight of the vehicle body. [0003] At present, the grades of domestic cast magnesium alloys include ZM2, ZM3, ZM4, ZM6 and so on. These grades of alloys have the characteristics of good mechanical properties and casting properties. At the same time, because the β phase of ZM series magnesium alloys contains a certain amount of MgZr compounds with higher melting points or the combination of M...
