从已发表的文献中可以看出,含2～3％Th的镁合金的特点是在300～350℃之温度间隔内具有高的抗蠕变性能以及足够高的机械性能和工艺性能。 我们曾用测定瞬时硬度和持久硬度的方法研究了含钍的二元镁合金及某些除含有钍之外,尚含有铈、铝、钙和锌的三元镁合金[1]。 配制合金时曾采用了МГ1的纯镁。钍、铈和锰以中间合金形式加入合金中,而铝、钙、锌是以纯金属加
From the published literature, it can be seen that a magnesium alloy containing 2 to 3% Th is characterized by high creep resistance and sufficiently high mechanical and process properties at a temperature of 300 to 350 ° C. We have examined the binary magnesium alloys containing thorium and some ternary magnesium alloys containing cerium, aluminum, calcium and zinc in addition to thorium [1] by measuring the instantaneous hardness and permanent hardness. The pure magnesium of МГ1 was used to prepare the alloy. Th, cerium and manganese are added to the alloy in the form of an intermediate alloy, while aluminum, calcium and zinc are based on pure metal
