  2. 1. Computational modelling of hot isostatic pressing

    Author : Ales Svoboda; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : The objective of this work was the development of a computer aided concurrent engineering system (CACE) for manufacturing simulation with particular application to hot isostatic pressing (HIP). The physical and mechanical phenomena connected with the hot isostatic pressing of powder metallurgical materials are analysed. READ MORE

  4. 2. Weldability of Cast Superalloys - Effect of homogenization heat treatments on hot cracking susceptibility of cast Alloy 718, ATI® 718Plus®, and Haynes® 282®

    Author : Sukhdeep Singh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot ductility; Segregation; Homogenization; Boron; Gleeble; Welding; Nickel-based superalloys; Varestraint; Hot cracking; Hot isostatic pressing; Niobium;

    Abstract : Precipitation hardened Ni- and Ni–Fe-based superalloys are used in high-temperature sections of aero engines owing to their superior mechanical properties compared to those of the other alloys. However, their better mechanical performance is accompanied by its own challenges during the manufacturing process. READ MORE

  5. 3. Continuous Fibre Reinforced Oxide/Oxide Composites

    Author : Magnus Holmquist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polycrystalline oxide fibre; zirconia; single crystal oxide fibre; hot isostatic pressing; hot pressing; alumina; mullite; sapphire; tape casting; interface; VibroIntrusion; interphase; continuous fibre reinforced ceramic composite; mechanical properties; oxide fibre; ceramic matrix composite;

    Abstract : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. READ MORE
