Ceramic-Reinforced γ-TiAl-Based Composites: Synthesis, Structure, and Properties.

In this study, new multilayer TiAl-based composites were developed and characterized. The materials were produced by spark plasma sintering (SPS) of elemental Ti and Al foils and ceramic particles (TiB₂ and TiC) at 1250 °C. The matrix of the composites consisted of α₂-TiAl and γ-TiAl lamellas and reinforcing ceramic layers.
