Tib2 as catalyst
Webb8 mars 2024 · The “rich Ti, B area” is essential for the nucleation and growth of TiAl3 and TiB2. Blocky TiAl3 was obtained and its average size was 4.7 μm based on the halide salt route. In the Ti-sponge route, the nucleation of TiAl3 mainly depends on the mutual diffusion of Al and Ti, and TiAlx forms around pure Ti particles, i.e., the so-called …
