1. 6. Modelling the influence of porosity on fatigue strength of sintered steels

   University essay from Uppsala universitet/Strukturkemi

   Author : Emily Hall; [2019]
   Keywords : Fatigue; Powder metallurgy; PM; sintered steels; fracture mechanics; porosity; metal powders; fatigue strength; fatigue limit; utmattning; pulvermetallurgi; metallpulver; utmattningsgräns; brottmekanik; porositet; sintring;

   Abstract : The pores in pressed and sintered components constitute weak points in the material since the stress concentration is larger than the nominal stress there. Therefore, fatigue cracks initiate at the pores. Specifically, it can be assumed that the fatigue cracks initiate at the largest pore in the stressed volume. READ MORE

3. 7. Sustainability of Additive Manufacturing : Electron Beam Melting of IN718

   University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

   Author : Linda Alsing; Sandra Johansson Storm; [2019]
   Keywords : Additive manufacturing; aerospace industry;

   Abstract : The purpose of this thesis is to examine and describe the process of Additive Manufacturing (AM) and the energy use in the production of parts manufactured with the Electron Beam Melting (EBM) technology in particular IN718, which is a Nickel-based superalloy with specification according to UNS n07718 that is used in the aerospace industry. The objectives also include a brief overview of powder bed AM methods and a sustainability analysis. READ MORE

4. 8. Evaluation of Different Concepts for Pressed and Sintered Connecting Rods

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Mattias Rehn; [2019]
   Keywords : Connecting Rod; Con Rod; Fatigue; Buckling; Manufacturing; Höganäs AB; CAD; FEM; FEA;

   Abstract : Connecting rod are found in most combustion engines and transmits thrust from the piston to the crankshaft. The connecting rod needs to withstand forces from the piston and inertia forces which results in axial tension, compression stresses and bending. READ MORE

5. 9. Investigation and Evaluation of Metal Powder Characterization Techniques : Currently available at the KTH Department of Material Science and Engineering

   University essay from KTH/Materialvetenskap

   Author : Leo Hultén; Philip Jansson; [2018]
   Keywords : Powder Metallurgy; Metal Powder Characterisation; Evaluation; Investigation; Metal Powder Characterisation Techniques; assessment;

   Abstract : The KTH Department of Materials Science and Engineering has lacked powder metallurgy research for many years, and as this field is constantly gaining in importance, such research needs to be reestablished. This requires the department to be able to accurately and efficiently characterize the properties of a powder, such as size distribution and composition, and in the short term, this needs to be done using non-specialized equipment.

6. 10. Intermetallic Compound Formation in Ni-Ti-Fe Powder Mixtures

   University essay from Lunds universitet/Materialteknik

   Author : Tea Bertilsson; [2018]
   Keywords : Phase Evolution; Ni-Ti-Fe System; Intermetallics; Powder Metallurgy; Reactive Sintering; DSC; SEM; EDS; XRD; Technology and Engineering;

   Abstract : The Ni-Ti system has a broad range of applications, in areas as diverse as biomedicine and robotics. This is in large due to the NiTi intermetallic compound, which exhibits the shape memory effect. In addition to this property, the intermetallic compound is also biocompatible, has good mechanical properties and good corrosion resistance. READ MORE
