Microstructural evolution and competitive reaction behavior of Ti-B4C system under solid-state sintering

Abstract
Abstract By using experimental investigations and theoretical calculations, microstructural evolution and competitive reaction behavior of Ti-B4C system under solid-state sintering is confirmed. Firstly, B4C decomposes into B and C atoms followed by diffusing into Ti side immediately, and TiB whiskers form in Ti matrix. Then, Ti atoms diffuse into B4C via vacancies left by the diffused B and C atoms, leading TiB2 and carbon substance to form in B4C side. Subsequently, reaction product carbon diffuses into Ti side and concentration of C in Ti side increases accordingly, resulting in the formation of TiC particles in Ti matrix. With further processing of reaction, both amount and size of products increases gradually. When TiB2 phases grow into a monolithic layer, diffusion behavior between Ti and B4C is inhabited, carbon presents to be a loose layer between un-reacted B4C and TiB2, and the in situ reaction also stops finally.
