摘要： Aluminium alloy containing Mg and Si, in particular useful for extrusion purposes containing in wt%.: Mg 0,3 - 0,5; Si 0,35 - 0,6; Mn 0,02 - 0,08; Cr 0,05; Zn 0,15; Cu 0,1; Fe 0.08 - 0,28 and in addition grain refining elements up to 0,1 wt% and incidental impurities up to 0,15 wt%. The manganese (Mn), within the specified limits, has an additional positive effect on the extrudability of an AlMgSi alloy. In addition to promoting the transformation of the AlFeSi intermetallic phases, AlMnFeSi dispersoid particles are formed during homogenisation. These particles are acting as nucleation sites for Mg 2 Si particles during cooling after homogenisation. In a high quality billet the Mg 2 Si particles formed during cooling after homogenisation should easily dissolve during the preheating and the extrusion operation before the material reach the die opening.
摘要翻译：含有Mg和Si的铝合金，特别适用于以wt％计：Mg 0.3-3.5的挤出用途; Si 0,35 - 0,6; Mn 0.02-0.08; Cr 0,05; Zn 0,15; Cu 0.1; Fe 0.08-0.28，另外晶粒细化元素高达0.1重量％，杂质高达0.15重量％。在规定限度内，锰（Mn）对AlMgSi合金的挤出性具有额外的积极作用。除了促进AlFeSi金属间化合物相的转变之外，AlMnFeSi分散质颗粒在匀质化过程中形成。这些颗粒在匀浆后的冷却过程中充当Mg2Si颗粒的成核位点。在高质量的钢坯中，匀浆后冷却过程中形成的Mg2Si颗粒在材料到达模具开口之前，在预热和挤出操作过程中应易于溶解。
