6. 4. On customization of orthopedic implants - from design and additive manufacturing to implementation

   Author : Marie Cronskär; Mats Tinnsten; Mikael Bäckström; Lars-Erik Rännar; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Patient-specific implants; Additive manufacturing; Electron beam melting; Multibody musculoskeletal analysis; Orthopedic implants; Clavicle; Finite element analysis; Computer aided design; Osteosynthesis plate; Hip stem implants;

   Abstract : This doctoral thesis is devoted to studying the possibilities of using additive manufacturing (AM) and design based on computed tomography (CT), for the production of patient-specific implants within orthopedic surgery, initially in a broad perspective and, in the second part of the thesis focusing on customized clavicle osteosynthesis plates. The main AM method used in the studies is the Electron Beam Melting (EBM) technology. READ MORE

7. 5. Eutectic Modification of Al-Si casting alloys

   Author : Jenifer Barrirero; Frank Mücklich; Magnus Odén; Franz Jospeh Feikus; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Aluminum alloys with silicon as the major alloying element are the most widely used aluminum casting alloys. The eutectic phase in these alloys is formed by hard and brittle silicon plates in an aluminum matrix. Such silicon plates can act as crack propagation paths deteriorating the toughness of the material. READ MORE
