摘要

为了研究粗镁直接熔炼AM60B镁合金锭各个部分力学性能及夹杂物的分布

在粗镁熔炼AM60B镁合金锭的左、中、右各部取样

进行拉伸和冲击试验。采用SEM观察断口形貌.并用EDS分析镁合金中的夹杂物分布。结果表明

粗镁直接熔炼AM60B镁合金锭中间部分抗拉强度和屈服强度较两侧稍低一些

左、中、右各部分的伸长率依次增大。AM60B镁合金锭中间部分冲击韧度较两侧高一些。镁合金锭左侧部分含有硅夹杂物

中间部分有碳氧化合物

右侧部分有溶剂夹杂物。

Abstract

In order to investigate mechanical properties and the distribution of inclusions in the different parts of AM60B magnesium alloy ingots directly smelted from crude magnesium

the samples were cut from the left

middle and right part of the AM60B magnesium alloy ingots

and tensile and impact testing were conducted on different parts. The fracture morphology of the different parts cut from the AM60B magnesium alloy ingot was observed by means of SEM. And the distribution of the inclusions in the magnesium alloy was analyzed by means of EDS. The results show that tensile strength and crack strength in the middle part of AM60B magnesium alloy ingots directly smelted from crude magnesium are lower than those in the left and right parts

and elongation in the left

middle and right parts is increased gradually. Impact toughness in the middle part of the AM60B magnesium alloy ingots is higher than those in the left and right parts. The inclusions with Si exist in the left part of magnesium alloy. The inclusions of carbon and oxygen compounds exists in the middle part

and the solvent inclusions exists in the right part of magnesium alloy.
