Efforts to improve the properties and reliability of piezoelectric materials have often concentrated on processing dense ceramic material by techniques such as fine particle size powder production, grain size control, hot pressing, hot isostatic pressing and controlled atmosphere sintering [1–3]. However, it has been shown that lowering the density and introducing significant amounts of open po...

In this paper we report on the synthesis and characterization of Ti3GeC2, Ti3Si0.5Ge0.5C2, and Ti3Si0.75Ge0.25C2 solid solutions. Polycrystalline, fully dense, predominantly single phase samples of Ti3Si0.5Ge0.5C2, Ti3Si0.75Ge0.25C2, and Ti3GeC2 of varying grain sizes were fabricated by reactive hot isostatic pressing (HIP) or hot pressing of Ti, C, SiC, and Ge powders. Based on the lattice par...

Titanium alloys exhibit mechanical and physical properties that fit structural applications demanding light-weight, corrosion resistance and biocompatibility. Ceramic reinforcements can further improve some of these mechanical properties, such as wear resistance, specific stiffness and specific strength. In comparison to continuous reinforced titanium alloys, the particle reinforced alloys (PRT...
