2. 1. Process Development for Electron Beam Melting of 316LN Stainless Steel

   Author : Stefan Roos; Lars-Erik Rännar; Andrei Koptioug; Jonas Danvind; Lars Pejryd; Mittuniversitetet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; beam deflection rate; electron beam melting; energy input; material properties; microstructure; powder bed fusion; process parameters; 316LN stainless steel;

   Abstract : Additive manufacturing (AM) is a technology that inverts the procedure of traditional machining. Instead of starting with a billet of material and removing unwanted parts, the AM manufacturing process starts with an empty workspace and proceeds to fill this workspace with material where it is desired, often in a layer-by-layer fashion.

4. 2. SURFACE PROPERTIES OF IMPLANTS MANUFACTURED USING ELECTRON BEAM MELTING

   Author : Rebecca Klingvall Ek; Lars-Erik Rännar; Mikael Bäckström; Jaan Hong; Felicia Suska; Mittuniversitetet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron beam melting; blood coagulation; bone ingrowth; surface roughness; process parameters;

   Abstract : This thesis summarizes the results concerning the manufacture of medical implants for bone replacement using electron beam melting (EBM) which is an additive manufacturing (AM) technology, and aims to satisfy the engineering needs for the medical functionality of manufacturing technology. This thesis has focused on some microscopic properties for surfaces and bone integration. READ MORE

5. 3. Electron beam melting of Alloy 718 : Influence of process parameters on the microstructure

6. 4. Characterisation of Nickel-Based Superalloys Manufactued by Electron Beam Melting

   Author : Annika Strondl; Chalmers University of Technology; []
   Keywords : 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

7. 5. A study on Electron Beam Melted Ti-6Al-4V

   Author : Adnan Safdar; Hållfasthetslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ti-6Al-4V; Electron beam melting; Microstructures; Surface roughness; phase filed modelling.;

   Abstract : The work presented in this dissertation is concerned with the microstructures and surface roughness of test slabs of Ti-6Al-4V produced by one of powder based Additive Manufacturing (AM) technique namely electron beam melting (EBM). The effects of process parameters of a EBM system and geometry factors of a EBM build such as slabs’ thickness and height etc. READ MORE
