Influence of High Pressure Hot Compaction on Microstructure of Al-Si-Ni-Mm Alloys

Article Preview

Abstract:

Nanocrystalline Al-Si-Ni-Mm alloys have been intensively investigated in recent years. Nanocrystalline Al - based alloys containing silicon (Si), rare earth metal (RE) and late transition metal (Ni), have high tensile strength and good wear resistance. The aim of the work was to manufacture bulk nanocrystalline Al-Si-Ni-Mm system alloys and determine the influence of hot compaction at high pressure on the microstructure. The bulk nanostructured Al73Si19Ni7Mm1 and Al72Si19Ni7Mm2 alloys were produced by high pressure hot compaction of ball milled nanocrystalline ribbons.
