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.
