高导热Mg-Zn-Mn变形镁合金及其制备方法
摘要：
一种经济导热、无毒适用于生物植入的镁合金，该镁合金的成分含量为：Zn的含量为0.05～8wt.%，Mn的含量控制在0.1～2.2wt.%；其余为Mg及其它不可避免的杂质元素(除Mg-(5-6.5wt.%)Zn-(0.8-1.5wt.%)Mn)。以纯镁锭、纯Zn锭、纯Mn颗粒或者Mg-Mn中间合金为原料；将纯镁锭熔化后添加Mn、Zn进行合金化净成型后热处理，或制成铸锭均匀化处理变形加工后热处理。本发明所涉及的Mg-Zn-Mn镁合金重力铸造铸锭在25℃条件下，导热率大于100W.(m.K)-1，抗拉强度为199.5～283MPa，延伸率为6%～23.5%，导热性能优异、综合性能良好、铸锭制作工艺简单，是制作电子器件结构材料散热件以及各种散热片的备选材料，也可用作医用生物植入材料。
摘要（英）：

An economic, heat-conducting and nontoxic magnesium alloy suitable for bio-implantation is disclosed. Components of the magnesium alloy comprise, by weight, 0.05-8% of Zn, 0.1-2.2% of Mn and the rest of Mg and other unavoidable impurity elements (except Mg-(5-6.5wt%)Zn-(0.8-1.5wt%)Mn). A pure magnesium ingot, a pure Zn ingot, pure Mn particles or an Mg-Mn intermediate alloy is used as a raw material; after the pure magnesium ingot is molten, Mn and Zn are added and alloying net-shaping postheat-treatment is carried out, or prepared ingot homogenization deformation-processing postheat-treatment is carried out. According to the Mg-Zn-Mn magnesium alloy gravity casting ingot under the condition of 25 DEG C, heat conductivity is greater than 100 W.(m.K)<-1>, tensile strength is 199.5-283 MPa, elongation is 6-23.5%, heat-conducting property is excellent, comprehensive performance is good, and ingot preparation technology is simple. The product is a candidate material for manufacturing electron device structural material heat-sinks and various cooling fins and also can be used as a medical biological implant material.
