Development Modes of Prior Free Sintering to Form a High-Density Fine Grain Ceramics after HIP

Article Preview

Abstract:

In this paper the two methods of pre-operation green samples to hot isostatic pressing (HIP) were investigated. The influence the method of formation (uniaxial and cold isostatic pressing) and the temperature-time parameters on property of samples was analyzed. Structural investigation was carried out and physical properties of samples were defined. The recommendations for pre-operation and uses of sintering modes samples for HIP were given.
