    Keywords : carbon content; wear performance; carburized steel; dry contact interface; threaded connections; drill rods; samples; shot peening; production process; twin-disc wear tester; RPM; operating conditions; wear rate; surface topography; hardness; optical analysis; light optical microscopy; scanning electron microscopy; surface carbon content; microstructural changes; frictional heat; contact pressure; wear mechanisms; plastic deformation; adhesive scratching; material removal; delamination;

    Abstract : This thesis work was conducted at Luleå University of Technology in collaboration with Sandvik Rock Tools. The aim of the work was to determine the influence of carbon content on the wear performance in carburized steel in the dry contact interface of threaded connections between drill rods. READ MORE

  3. 2. Long term aging and creep exposure for advanced heat resistant alloys : A phase analysis

    University essay from Uppsala universitet/Institutionen för materialvetenskap; Uppsala universitet/Institutionen för kemi - Ångström

    Author : Daniel Lundberg; Filip Wilson; Hjalmar Gunnarsson; Leo Sjörén; Robin Xu; Erik Djurberg; [2021]
    Keywords : Austenitic stainless steel; ferritic steels; nickel based alloys; creep; ageing; XRD; SEM EDS; LOM;

    Abstract : This project was ordered by Sandvik Materials Technology and was performed by a group of students at Uppsala university. The purpose of the project was to study precipitation behavior and structure stability in six advanced heat resistant alloys. Each sample were subjected to a creep rupture test in 600 or 700°C depending on the alloy type. READ MORE

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

    University essay from Högskolan Dalarna/Institutionen för information och teknik

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

    Abstract : 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. READ MORE

  5. 4. Some Study related to Refractory Waste Management in Sweden : A move towards a greener and sustainable Swedish steel industry

    University essay from KTH/Materialvetenskap
