   Abstract : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. READ MORE

4. 2. The relation between microstructure and mechanical properties of cobalt- and nickel-rich Co-Ti-C and Ni-Ti-C alloys

   Author : Birgit E. Jacobson; Linköpings universitet; []
   Keywords : ;

   Abstract : Age-hardening processes up to l000°c which might be important in the binder phase of the Co-Ti-C and Ni-Ti-Chard metal systems have been studied mainly by high voltage electron microscopy, (HVEM), optical microscopy (OM) and scanning electron microscopy (SEM) as well as by micro-and macrohardness measurements and tensile testing at room and elevated temperatures (500°-800°). In addition,the allotropic transformation of cobalt has been followed by X-ray diffraction in order to permit a more complete interpretation of the changes in microstructure reflected in the mechanical testing.
