Abstract
Abstract Bulk Ti3AlC2 was fabricated by either hot-pressing of synthesized Ti3AlC2 powders (HP), to produce oriented-grain- texture, or in-situ reaction hot-pressing of Ti/Al/TiC mixture (RHP), to produce relatively untextured structure. Although a process window for controlling microstructure, such as grain size and textured microstructure, in single phase of Ti3AlC2 is narrow due to the evaporation of Al during the sintering, we successfully obtained single phase Ti3AlC2 with tailored microstructures by optimizing the composition of the starting mixture. The correlation between Vickers hardness and microstructure was investigated. A significant indentation size effect (ISE) was observed in both HP and RHP samples. Hardness anisotropy owing to the orientation effect of plate-like grains was confirmed only in highly textured Ti3AlC2 with platelet length of 42 µm and was in good agreement with that reported in the single crystal.
