Abstract

The invention discloses a heat-proof cast magnesium alloy. The heat-proof cast magnesium alloy comprises, by weight, 0.5-2% of silicon, 2.5-5.5% of aluminum, 5-8% of zinc, 0.2-0.5% of bismuth, 0.1-0.5% of manganese, 3-5% of gadolinium, 0.2-1.5% of calcium, below 0.02% of impurities, and the balance of magnesium. The heatproof property of the magnesium alloy is effectively improved by optimizing the composition and the ratio of the alloy, and the comprehensive mechanical properties of the high-strength cast magnesium alloy in the invention are significantly higher than those of currently reported cast magnesium alloys.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a heat-resistant casting magnesium alloy. Background technique [0002] With the rapid development of the global economy, how to reduce energy consumption, improve resource utilization, reduce environmental pollution and save limited resources is a very urgent problem facing all mankind, and the lightweight of products provides a very effective way to solve this problem way. Magnesium alloy is known as "the green engineering material of the 21st century" because of its low density, high specific strength and specific stiffness, good damping and shock absorption performance, good electromagnetic shielding performance, and excellent machining performance. Utilizing valuable resources, it is widely used in the automotive industry, communication electronics, and aerospace and other fields. However, due to the low strength and poor heat resistance of magnesium alloys, its applicatio...
