摘　　要：利用PoDFA离线测渣分析方法对7055铝合金熔体中的渣进行检测分析。通过过滤铝合金熔体将夹杂物富集,然后采用物理金相方法对夹杂物进行鉴别分析,建立7055铝合金熔体夹杂物形貌特征与图谱。结果表明7055铝合金熔体主要含有氧化膜、氧化镁、尖晶石、TiB_(2)、耐火材料夹杂。The inclusions in 7055 aluminum alloy melt were detected and analyzed by PoDFA offline inclusions detection analysis method.The inclusion is enriched by filtering the aluminum alloy melt,and then the inclusion is identified and analyzed by physical metallographic method to establish the morphology characteristics and map of 7055 aluminum alloy melt inclusion.The results show that 7055 aluminum alloy melt mainly contains oxide films,magnesium oxides,spinel,TiB_(2) and refractory materials inclusions.
