2. Influence of deformation and environmental degradation of Inconel 792
Sammanfattning : Industrial gas turbines are often used as a mechanical drive for pumps and compressors or in power generation as an electric power supply. The gas turbine has for many years been a popular engine due to its flexibility with respect to different types of fuel and due to a design, that enables a high power-to-weight ratio. LÄS MER
3. Laser powder bed fusion processing and heat treatment of Ni-base superalloys: microstructure and properties
Sammanfattning : Nickel-base superalloys are indispensable materials for the energy and aerospace industries. The additive manufacturing (AM) of these materials by powder bed fusion – laser beam (PBF-LB) presents a valuable opportunity to improve component performance and ease manufacturing and supply chain complexity in these industries.

4. Characterisation of Nickel-Based Superalloys Manufactued by Electron Beam Melting
Sammanfattning : Nickel-based superalloys have been manufactured by electron beam melting (EBM). EBM is an additive manufacturing process for direct production of metal parts. The part is build up by successive melting of metal powder layers in a vacuum chamber using electron beam. LÄS MER
5. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments
Sammanfattning : Traditionally, costly experimental procedures have been followed in industry to optimise the machining operations to secure the maximum efficiency in production line, while the functional requirements of the machined surfaces are fulfilled. In recent years, development of robust numerical techniques such as Finite Element Method (FEM) and advances in computing capacity of computers have made it possible to simulate the machining operations under operational conditions.
