Microstructure and Mechanical Properties of Composites Obtained by Spark Plasma Sintering of Al–Fe66Cr10Nb5B19 Metallic Glass Powder Mixtures

At present, metallic glasses are evaluated as alternative reinforcements for aluminum matrix composites. These composites produced by powder metallurgy via consolidation of glass-aluminum mixtures. In most studies, the goal has been to preserve glassy state reinforcement during consolidation. However, it is also interest track structure evolution these when partial interaction between and glass allowed sintering The present work was aimed study microstructure mechanical properties obtained spark plasma (SPS) Al-20 vol.% Fe66Cr10Nb5B19 mixtures compare materials, in which no significant Fe-based alloy occurred, with those featuring reaction product layers different thicknesses. Composite materials were consolidated SPS at 540 570 °C. followed forging, interfacial products thicknesses, glass-free sintered comparatively analyzed conclude on influence microstructural features their strength.
