  1. 6. The Effect Of Sub Tx Heat Treatments On The Magnetic Properties Of An Fe-based Bulk Metallic Glass

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Grunditz Jakob; [2022]
    Nyckelord :Bulk metallic glass; annealing; heat treatment; MOKE; Magnetic; Fe-based; Coercivity; Magnetic properties; Magnetic saturation; coercivity; saturation; magnetic coercivity; sub crystallization; sub Tx; Relaxation;

    Sammanfattning : Metallic glasses produced with Selective Laser Melting (SLM) often contain internal mechanic stress. This internal stress can have an impact on the magnetic properties of the material due to its connection to the magnetic anisotropy of the material. LÄS MER

  2. 7. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Soumen Ghosh; [2022]
    Nyckelord :Experimental fluid mechanics; Pressure drop; friction factor; Internal flow; fully developed flow; turbulent flow; Fluid mechanics; Ideal gas; Moody s chart; Additive manufacturing; compressible flow; turbine blade cooling; mini channel;

    Sammanfattning : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. LÄS MER

  3. 8. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Jijesh Rajan; [2022]
    Nyckelord :Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Sammanfattning : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. LÄS MER

  4. 9. Mechanical and tribological characterization of additivemanufactured Co-free tool steels aimed for cutting tool bodies

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Mayur Mane; [2021]
    Nyckelord :Co-free maraging steels; Co-free W360 AMPO alloy; hot-work tool steel; Selective laser melting; microstructure; wear;

    Sammanfattning : Additive manufacturing (AM) is an emerging and interesting technology that enables some of theproduct development projects (PDPs) to produce products that have mechanical and tribologicalproperties comparable to products that are conventionally manufactured. Selective laser melting(SLM) is an additive manufacturing technology that is predominantly used for the production of metalbased components (i. LÄS MER

  5. 10. Macro composites for crushing - additive manufacturing of hard phase : Development and testing of macro composites for crushing purposes

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Maria Wojtowicz; [2021]
    Nyckelord :stone; rock; crushing; tribology; jaw crusher; selective laser melting; SLM; additive manufacturing; steel; macro composite; bronze;

    Sammanfattning : During this master thesis a crushing material composite was developed in order to determine if a specific design consisting of a pointy hard phase with a ductile phase in between can reduce the load needed to crush stone and therefor decrease the energy consumption during stone crushing. The steel hard phase (ASP 2012) was printed using an additive manufacturing method called selective laser melting (SLM). LÄS MER
