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. Novel approaches for achieving full density powder metallurgy steels

   Author : Maheswaran Vattur Sundaram; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cr- and Mo-alloyed PM steels; vacuum sintering; high density; full density; hot isostatic pressing.; cold isostatic pressing; liquid phase sintering; master alloy; double pressing-double sintering; powder metallurgy steels; sintering; water atomised powder;

   Abstract : Powder metallurgy (PM) is one of the most resource-efficient methods for manufacturing structural components with complex shapes. The utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. READ MORE

5. 3. Net-Shape Consolidation of Water-Atomised and Gas-Atomised Steel Powder Towards Full Density

   Author : Anok Babu Nagaram; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot isostatic pressing; high temperature sintering; sintering atmosphere; cold isostatic pressing; Powder metallurgy; Prealloyed with Cr PM steel; high density; PM steel;

   Abstract : Powder metallurgy (PM) provides resource- and cost-efficient routes to create near-net shape products compared to conventional metal fabrication techniques. To improve the mechanical performance of PM steels, it is a prerequisite to enhance the density of the material. READ MORE

6. 4. Varestraint Weldability Testing of Cast Superalloys

   Author : Sukhdeep Singh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Varestraint; Hot Cracking; Welding; Alloy 718; Cast Superalloys; ATI® 718 PlusTM; HIP;

   Abstract : Precipitation hardened Ni- and Ni-Fe- based superalloys, used in hot structural components for aero engines, are subjected to hot cracking phenomena during manufacturing and specifically in welding. This type of cracking involves metallurgical reactions from the liquid phase in concomitance to weld restraints. READ MORE

7. 5. Hot isostatic pressing of ceramics and influence of glass encapsulation

   Author : Anna-Karin Westman; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Engineering Materials;

   Abstract : Hot isostatic pressing (HIP) is one of the industrial techniques for production of structural ceramics. A high quality of the as-HIPed surface is highly desirable, as it may make it possible to minimise or eliminate costly finishing machining. READ MORE
