Current work, aims at preparation and characterization of Al-Al3Ti in-situ metal matrix composites with varying percentage of in-situ Al3Ti (3 and 5%) reinforcement. The composites were prepared by the salt route involving reaction of commercial purity aluminum (99.7%) and potassium titanium flourate halide (K2TiF6) salt at a reaction temperature of 800°C and with 60min. holding time. The prepared composites were subjected to microstructural studies using Scanning Electron Microscope. Further, the work aims at evaluating mechanical properties of the prepared composites as per ASTM standards. Microstructural characterization using SEM revealed blocky morphology of Al3Ti intermetallics with fairly homogeneous distribution. Insitu Al-Al3Ti composites have shown better mechanical properties when compared to the unreinforced Al matrix.

Critical Regions

This literature review aims to summarize the research conducted on the production of locally reinforced ferrous castings based on metal matrix composites reinforced with TiC (TiC-MMCs). One way to improve the wear resistance of cast components is to reinforce critical regions locally with metal matrix composites (MMCs) without changing the toughness of the component core. The in situ method of self-propagating high-temperature synthesis is one of the main approaches for the production of this enhanced material. Using this approach, the reinforcement is formed from a powder compact inserted in the mold cavity. The temperature of the liquid metal then produces the combustion reactions of the powders, which promote the formation of the ceramic phase. This paper focuses on eight powder systems used to synthesize TiC: Ti-C, Ni-Ti-C, Ni-Ti-B4C, Fe-Ti-C/Fe-Cr-Ti-C, Cu-Ti-B4C, Al-Ti-C, and Al-Ti-B4C, and provides an overview of the methodologies used as well as the effect of processing variables on the microstructural and mechanical characteristics of the reinforcement zones.
