Tóm tắt

Interfacial diffusion has been evidenced in a eutectic-like Ni, Cr-TaC composite, using high resolution autoradiographic techniques. The structure of the fibre-matrix interface has been determined by using high voltage electron microscopy. The fibre-matrix interface has been shown to be a diffusion short circuit in the temperature range 700° C to 900° C.
