21. Mechanical Properties, Microstructures and Defects of Tool Steels Fabricated by Additive Manufacturing
Abstract : Additive Manufacturing (AM) has been gaining significant interest in the manufacturing of metallic materials in the recent years. From a techno-commercial standpoint, tooling is one of the areas with low production volumes but very high demands on part performance and complexity in design, all of which are characteristic for metal AM.

22. Nanostructured carbon materials prepared by hole-mask colloidal lithography
Abstract : Research and development of nanofabrication methods can be motivated both formanufacturing of commercially available products like micro electronic componentsand for development of model systems for fundamental and applied science. Thefabrication process developed during this work, hole-mask colloidal lithography(HCL), is primarily oriented towards the latter two, specifically for research in thefields of catalysis, nanoparticle plasmons, and bio- and fundamental physics.

23. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels
Abstract : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. READ MORE

24. Experimental study and simulation of sintering of 316L components produced by binder jetting
Abstract : Binder Jetting (BJT) is a multi-step Additive Manufacturing (AM) technique that is used for producing components with highly complex geometries and competitive final properties with high productivity when compared to other AM technologies. The first step provides the basic part geometric shape (BJT printing), and the next step (debinding and sintering) consolidates the part to reach final geometry and intended basic material properties.

25. Laser powder bed fusion processing and heat treatment of Ni-base superalloys: microstructure and properties
Abstract : 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.
