Scripta Materialia, 53(7), 841- 844.https://hdl.handle.net/10289/1399High purity Mg–Al type alloys have a naturally fine grain size compared to commercial purity alloys with the same basic composition. This is referred to as native grain refinement. It is shown that native grain refinement occurs only in magnesium alloys containing aluminium. The mechanism is attributed to the Al4C3 particles existing in these alloys.enMagnesiumGrain refiningNative grain refinementAl4C3Journal Article10.1016/j.scriptamat.2005.06.010
