  1. 1. Surface Finishing and Corrosion Resistance of 3D Printed Maraging Steel

    University essay from

    Author : Yinan Shao; [2020]
    Keywords : Surface finishing; corrosion resistance; selective laser melting; microstructure; maraging steel;

    Abstract : 3D printing, also known as additive manufacturing (AM), has got rapidly developed since 1987. Compared with conventional manufacturing methods, 3D printing provides some advantages such as increasing material utilization and less waste of material. READ MORE

  2. 2. Relation Between the Material in Press Hardening Dies and Fully Martensitic Transformation : Sheet properties of thick 3D-sheets in small series production

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Jesper Christensson; [2020]
    Keywords : hot stamping; press hardening; material properties;

    Abstract : This report evaluates the influence of the die material on the cooling rate and martensitic transformation of press hardened sheets. The goal was to increase the thicknesses of sheets that can form fully martensitic microstructure when press hardened. READ MORE

  3. 3. 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

  4. 4. Effect of Process Parameters on Contour Properties in Inconel 718 Structures Fabricated by Electron Beam Melting

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Karthik Vaidyalingam Arumugam; [2019]
    Keywords : Process Parameters; Contour Properties; Inconel 718; Electron Beam melting;

    Abstract : Additive Manufacturing (AM), commonly known as 3D printing is a production method that utilises repeated addition of layers in order to produce a final shape. AM utilises less raw material and does not have drawbacks such as tool wear and material wastage as seen in conventional machining. READ MORE

  5. 5. 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
