Microstructural Evolution and In Situ Formation of TiB and TiC in Ti─5Al─2.5Sn Alloy Processed by Powder Metallurgy

Advanced Engineering Materials, EarlyView.
Accelerated in situ formation of TiB and TiC in Ti–5Al–2.5Sn–B4C is driven by transient liquid phase formation, which enhances particle reactions and microstructural evolution. This process increases hardness and establishes a coupled relationship between sintering temperature and reinforcement content, strongly influencing porosity in the resulting ...

Development of a Cold Wall Reactor System for the Low‐Pressure Chemical Vapor Deposition of BN on SiC Fiber Tow

Advanced Engineering Materials, EarlyView.
A cold wall reactor is developed to coat a SiC fiber tow with BN by low pressure chemical vapor deposition. The precursor gas is triethylamine borane mixed with ammonia. The heating process induces a temperature gradient, with the temperature decreasing from the core to the surface of the multifilament tow.
