摘　　要：以3104铝合金铸造扁锭为例,介绍了变形铝及铝合金铸锭显微疏松检验试样的制备过程及其注意事项,并给出了在依据标准图谱判定显微疏松等级过程中容易出现的问题。通过对3104铝合金铸锭在各个方向进行检验,得出了显微疏松在变形铝及铝合金铸锭中的分布规律。Micro porosity testing sample preparation process and matters needing attention for deformation aluminium and aluminium alloy ingot were introduced with 3104 aluminium alloy ingot as an example.And problems easily produced when rating the micro porosity grade according to the standard grade pictures were listed.Finally distribution rule of micro porosity in deformation aluminium and aluminium alloy ingot was studied through micro porosity testing at different positions and direction of 3104 aluminium alloy ingot.
