    TEM study of the interface between HIPed silicon nitride and encapsulation borosilicate glass

    A transmission electron microscope study has been made of a silicon nitride component with 6 w/o yttrium oxide as a sintering aid hot isostatically pressed (HIP) with an encapsulation glass of borosilicate. Th...

    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...
