| Outline of Final Research Achievements |
Lightweight metal matrix composites reinforced with metallic glass fibers have been synthesized using different sintering techniques. The synthesis process of the novel nano-composites consists of a) mixing of powders of the crystalline matrix with metallic glass gas atomized fibers (nanowires and micron size particulates) using ball milling and b) compaction of the mixture of powders by sintering. Different sintering methods have been investigated. It was found that the powder metallurgy synthesis routes followed by either a) Spark Plasma Sintering (SPS) or b) induction heated - hot pressing (IH-HP), can produce composites with eliminated porosity and significantly enhanced mechanical behavior.
