Abstract

The invention discloses a high-strength high-plasticity Mg-Ca-Al-Zn-Mn-Ce wrought magnesium alloy and a preparation method of the high-strength high-plasticity Mg-Ca-Al-Zn-Mn-Ce wrought magnesium alloy, and belongs to the field of wrought magnesium alloy materials. The wrought magnesium alloy is prepared from, by mass, 0.50-3.20% of calcium, 0.30-3.50% of aluminum, 0.10-1.00% of zinc, 0.10-3.00% of manganese, 0.10-0.50% of cerium and the balance magnesium and inevitable impurities. The preparation method comprises the steps that a pure magnesium cast ingot is molten at first, after sufficientmelting, metal calcium, aluminum, zinc, cerium, manganese and the like are added, the mixture is sufficiently stirred and cast into a cast ingot, homogenizing treatment is carried out on the cast ingot, and extrusion is carried out through a reverse extrusion process to obtain a corresponding extruded section bar. The high-strength high-plasticity Mg-Ca-Al-Zn-Mn-Ce wrought magnesium alloy is prepared through the process of melting, homogenizing treatment and subsequent extrusion (reverse extrusion), the strength and toughness are enhanced, and the mechanical property is good.

Description

technical field [0001] The invention belongs to the field of magnesium alloy materials, in particular to a high-strength and high-plasticity Mg-Ca-Al-Zn-Mn-Ce deformed magnesium alloy and a preparation method thereof. Background technique [0002] With the increasingly serious environmental problems and the shortage of resources in recent years, energy saving and consumption reduction has become an urgent problem to be solved. The light weight of materials can greatly reduce the level of energy loss, which is of great significance to improving energy efficiency and protecting the environment. As the lightest metal structure material at present, the density of magnesium is only 1.74g / cm 3 , which is only 2 / 3 of aluminum and 1 / 4 of steel, has high specific strength and specific stiffness, good damping and shock absorption performance, good machining performance and good thermal conductivity, especially can be reused, so it is Known as the "green engineering material" of the ...
