1. Post-treatment of Alloy 718 produced by electron beam melting
Sammanfattning : Electron beam melting (EBM), a metal additive manufacturing (AM) process, has received considerable industrial attention for near net shape manufacture of complex geometries with traditionally difficult-to-machine materials. This has fuelled considerable academic interest in investigating EBM of Alloy 718, a nickel ironbased superalloy possessing an exciting combination of good mechanical behaviour and cost effectiveness.

2. Thermal post-treatment of Alloy 718 produced by electron beam melting
Sammanfattning : Additive manufacturing (AM) has emerged as a disruptive technology and it is a vital part in the present era of fourth industrial revolution, Industry 4.0. LÄS MER
3. Ni-based coatings for high temperature corrosion protection
Sammanfattning : Biomass/waste-fired boilers severely suffer from high temperature corrosion of critical load-bearing components, e.g. water-wall and superheater tubes, due to presence of Cl-containing corrosive species. LÄS MER
4. Laser-Directed Energy Deposition : Influence of Process Parameters and Heat-Treatments
Sammanfattning : Laser-Directed Energy Deposition (L-DED), an Additive Manufacturing (AM) processused for the fabrication of parts in a layer-wise approach has displayed an immense potential over the last decade. The aerospace industry stands as the primary beneficiary due to the L-DED process capability to build near-net-shape components with minimal tooling and thereby producing minimum wastage because of reduced machining.

5. Tribological behaviour of HVAF-sprayed WC-based coatings: : Role of process variables and binder chemistry
Sammanfattning : Tungsten carbide (WC) based metallic matrix coatings sprayed using high velocity air fuel (HVAF) technique have attracted increasing attention as they show excellent tribological performance in various wear conditions. In the HVAF method, particles’ in-flight temperature and velocity can be influenced by the process variables including nozzle configuration as well as feedstock particle size range. LÄS MER
