  1. 1. 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

  3. 2. Investigation Of Mechanical Properties And Microstructure Of Steel-Wires

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

    Author : Khalifa Maissara; [2021]
    Keywords : steel; heat treatment; quenching and partitioning; quenching and tempering; retained austenite; wear mechanisms; wear testing;

    Abstract : Wear and friction are among the major problems faced in several industries such as mining industry. This creates challenges to select better materials with good wear behavior in order to improve the service life of the components. READ MORE

  4. 3. Method to assess machinability of engineering steels using coated carbide tools

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Petra Hedberg; [2021]
    Keywords : Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

    Abstract : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested. READ MORE

  5. 4. Quenching and tempering hardness response of front axle steel beams : Different material properties during quenching and tempering

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

    Author : Simon Zemui; [2017]
    Keywords : Axle steel beams; hardness; Quenching; tempering;

    Abstract : The aim of this thesis was to investigate what the relation is between as-quench hardness and final surface hardness for steel beams is, depending on what tempering temperature is used. Also explain how chemistry, dimension and microstructure effects the final mechanical properties of the front axle beam. READ MORE

  6. 5. Influence of Ferrite Content on Fatigue Strength of Quenched and Tempered 42CrMoS4 Steel

    University essay from KTH/Materialvetenskap

    Author : Mithaq Elias Hanno; [2012]
    Keywords : Quenched and Tempered Steel; Fatigue strength; Ferrite Content;

    Abstract : Specimens of steel 42CrMoS4 were quenched from the austenite (γ) and the ferrite (α) + austenite + cementite phase fields to produce fully martensitic matrices with 0 – 14 % ferrite dispersed in the matrix. After tempering at 300°C or 600°C mechanical and fatigue properties were determined. READ MORE
