  1. 1. Influence of microstructure on surface characteristics in cold-deformed stainless steel tubes

    University essay from Lunds universitet/Materialteknik

    Author : Fredrik Ottenklev; [2019]
    Keywords : Cold deformation; surface roughness; strain; microstructure; austenitic stainless steel; grain rotation; Technology and Engineering;

    Abstract : Cold deformation of metals is known to induce roughness on their free surface. In some of the processing equipment of Tetra Pak processing systems, tubes of austenitic stainless steel 316L are used. During the production of this processing equipment, such tubes are occasionally cold-deformed. READ MORE

  2. 2. Experimental and Theoretical Investigation of Selective Laser Melted Uddeholm Dievar ®

    University essay from KTH/Materialvetenskap; KTH/Materialvetenskap

    Author : Sanjin Pepić; Otto Ridemar; [2019]
    Keywords : Uddeholm Dievar®; Additive manufacturing; AM; Selective laser melting; SLM; Gas-atomization; Hot-work tool steel; Uddeholm Dievar®; Additiv tillverkning; AM; Selective laser melting; SLM; Gas- atomisering; Varmarbetsverktygsstål;

    Abstract : The main problem encountered in this thesis is the lack of research and knowledge of selective laser melted-printing with Uddeholm Dievar®. This absence of information could cause issues regarding quality and properties of the alloy as well as uncertainty regarding an appropriate heat treatment cycle. READ MORE

  3. 3. Compact 3D Microscopy for Planetary Exploration

    University essay from KTH/Rymdteknik

    Author : Gustav Pettersson; [2018]
    Keywords : ;

    Abstract : We propose using grain-of-sand-scale microscopy (1-micrometre resolution) to study the microstructure and composition of planetary material in a fast, in-situ, solid-state device. We have constructed a small and light prototype instrument (100 grams, 0. READ MORE

  4. 4. Self-Lubricating Properties of Laser Claddings for High Temperature Forming Processes

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

    Author : Tugce Caykara; [2018]
    Keywords : self-lubricating; steel; aluminium; friction; wear; high temperature; hot forming;

    Abstract : This thesis summarizes the work done on tribological characterization of multifunctional hardfacing coatings with self-lubricating properties, intended for use in mechanical components operating in high temperature applications for which conventional lubricants are no longer effective. Deposition techniques like laser cladding have a great potential in reworking/repair of high value industrial components in order to extend their lifetime. READ MORE

  5. 5. Evaluation of mechanical and microstructural properties for laser powder-bed fusion 316L

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Philip Eriksson; [2018]
    Keywords : Additive Manufacturing; Laser Powder-Bed Fusion; L-PBF; 316L; Mechanical Properties;

    Abstract : This thesis work was done to get a fundamental knowledge of the mechanical and microstructural properties of 316L stainless steel fabricated with the additive manufacturing technique, laser powder-bed fusion (L-PBF). The aims of the thesis were to study the mechanical and microstructural properties in two different building orientations for samples built in two different machines, and to summarize mechanical data from previous research on additive manufactured 316L.
