The influence of rapidly solidified Ribbons pre-treatment on structure of Bulk AlFeMm alloys prepared by Powder Metallurgy

Popis výsledku v původním jazyce

Rapidly solidified AlFe7Mm4 ribbons were prepared by melt spinning process. The ribbons were composed from super saturated solid solution of alloying elements in Al matrix, stable intermetallic phases and metastable quasicrystalline phases. Both metastable phases can potentially provide self-healing properties to the material - super saturated solid solituon by precititation and quasicrystals by decomposition to stable phases. Key problem of processing such materials is to preserve the microstructure of rapidly solidified material during its compaction. Spark plasma sintering enables powder solidification in very short time - in range of few minutes. This article describes the best way of raidly solidified ribbons before SPS compaction to obtain bulk material. The ribbons were solidified in the initial state and after cryo-milling. Ball-milling before of rapidly solidified ribbons was also tested. Vickers hardnes HV0.01 was also evaluated. Cryo-milling was chosen as an optimal pre-treatment before compaction by SPS. © 2018.
