- Abstract
An in situ short fiber reinforced brazing technique by taking advantage of reaction between ZrB2 and Ti has been developed for joining ZrB2- SiC ceramic and Ti6Al4V alloy. The Ag- Cu eutectic alloy was used as brazing interlayer to realize controllable growth of TiB in Ti-rich environment. The microstructural evolution of the joint was divided into four stages as experiments performed from 840°C to 920°C. The diffusion behaviors of Ti and B may play an important role on the preferential growth of TiB whiskers during brazing. The statistics of the length of TiB showed that a rapid growth appeared at 880°C. The accommodation to the coefficients of thermal expansion by TiB whiskers was evaluated and the shear strength of the joints was tested.
