2. 1. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

   Author : Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

   Abstract : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. READ MORE

4. 2. Additively Manufactured Inconel 718 : Microstructures and Mechanical Properties

   Author : Dunyong Deng; Johan Moverare; Ru Lin Peng; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Additive manufacturing (AM), also known as 3D printing, has gained significant interest in aerospace, energy, automotive and medical industries due to its capabilities of manufacturing components that are either prohibitively costly or impossible to manufacture by conventional processes. Among the various additive manufacturing processes for metallic components, electron beam melting (EBM) and selective laser melting (SLM) are two of the most widely used powder bed based processes, and have shown great potential for manufacturing high-end critical components, such as turbine blades and customized medical implants.

5. 3. Characterisation of Nickel-Based Superalloys Manufactued by Electron Beam Melting

   Author : Annika Strondl; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEM; electron beam melting; APFIM; EBSD; XRD; DTA; nickel-based superalloys; SEM; additive manufacturing; EDS;

   Abstract : 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. READ MORE

6. 4. Additive manufacturing of Ni-based Superalloys- an analysis of parameter and strategy driven properties in Electron Beam Melting Process

   Author : Xiaoyu Zhao; Amir Rashid; Carolin Körner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam melting; Super-alloys; process optimization; surface defects; subsurface defects; mechanical properties; thermal stresses; thermal deformation; Production Engineering; Industriell produktion;

   Abstract : Metal AM processes produce significantly rough surfaces as compared to wrought or machined components. Currently, the as-EBM surfaces are extremely rough and consequently, the as-built components could not be directly used as commercial products. The state-of-the-art research has focused primarily on deeply machined (DM) samples. READ MORE

7. 5. Residual Stress Distributions in Additively Manufactured Parts : Effect of Build Orientation

   Author : Prabhat Pant; Ru Lin Peng; Johan Moverare; Kjell Simonsson; Jonathan Almer; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM;

   Abstract : Additive manufacturing (AM) of parts using a layer by layer approach has seen a rapid increase in application for production of net shape or near-net shape complex parts, especially in the field of aerospace, automotive, etc. Due to the superiority of manufacturing complex shapes with ease in comparison to the conventional methods, interest in these kinds of processes has increased.
