一种提高金属合金导热性能的方法
摘要：
本发明公开了一种提高低合金含量金属合金导热性能的方法———人工时效热处理，该方法适用于主元素质量百分比占比大于85wt.％的多元合金化金属合金，如镁合金、铝合金与钛合金，人工时效热处理温度控制在100～250℃范围以内，时效时间控制在2～96小时范围内。根据不同加工途径得到的金属合金经时效处理后，使得合金中过饱和固溶体所涉及合金元素析出，或使得合金中残余加工应力消除，均能使该合金室温热导率得到提高，一般能使室温热导率提高至少5％。
摘要（英）：

The invention discloses a method, namely artificial aging thermal treatment, for improving the heat-conducting property of metal alloy containing low-content alloy. The method is applicable to multielement alloying metal alloy with the mass percent of a host element greater than 85 wt. %, such as magnesium alloy, aluminium alloy and titanium alloy; the temperature of the artificial aging thermal treatment is controlled within the range of 100-250 DEG C, and the aging time of the artificial aging thermal treatment is controlled within the range of 2-96 hours. After the metal alloy obtained through different processing ways is subjected to artificial aging treatment, alloying elements related to supersaturated solid solution in the alloy separates out, or residual machining stress in the alloy is eliminated, so that the room temperature heat conductivity of the alloy is increased, and generally the room temperature heat conductivity can be increased by at least 5%.
