Stabilization Effect of Interfacial Solute Segregation on θ′ Precipitates in Al-Cu Alloys

Stabilization Effect of Interfacial Solute Segregation on θ′ Precipitates in Al-Cu Alloys

The effects of Sc, Mg and Si elements in an Al-Cu alloy have been studied by means of hardness tests and transmission electron microscopy analysis. The experimental results show that additions of Sc, Mg and Si can improve the heat resistance of the Al-Cu alloy. The Sc/Mg/Si segregation-sandwiched st...
