1. 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.

2. Powder degradation during powder bed fusion processing: impact of processing conditions and alloy composition
Sammanfattning : In the recent decade, powder bed fusion (PBF) metal additive manufacturing (AM) has attracted huge attention both from the industry and the research community. This effort has helped mature PBF technology as a potential alternative to conventional manufacturing processes as casting, machining, forging, etc. LÄS MER
3. High Performance Aluminium Alloys for Laser Powder Bed Fusion: Alloy Design and Development
Sammanfattning : Additive Manufacturing (AM), particularly Laser Based Powder Bed Fusion (LB-PBF) has proven to be a notable technology to produce novel microstructures and expand the ceiling of product design. However, the development of novel alloys in metal LB-PBF has not followed the same pace as development of product design. LÄS MER
4. Development of high performance aluminium alloys tailored for powder bed fusion-laser beam
Sammanfattning : The powder bed fusion-laser beam (PBF-LB) process has lately been regarded as a top choice for creating complicated structures which are not possible via conventional manufacturing. Nevertheless, the pace of alloys for PBF-LB has been slower. LÄS MER
