AEM investigation of ceramic/lncoloy 909 diffusional reactions after joining by HIP
Diffusion bonding by hot isostatic pressing (HIP) was performed between Incoloy 909 and five different ceramics. Two of the ceramics were composites made from powder mixtures of Si3N4 and either 60 vol% TiN or 50...
