  1. 1. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Atharva Kotasthane; [2023]
    Nyckelord :Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

    Sammanfattning : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. LÄS MER

  3. 2. Wear resistance of heat-treated Advanced High Strength Steels and casting

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Joan Morata Royes; [2020]
    Nyckelord :;

    Sammanfattning : The necessity to improve the durability of the machinery used in the milling industry has lead to several types of research. One study is focused on the plates that are located in the stationary and moving jaws of crushers to diminish particles sizes of Gneiss and Diabase rocks. LÄS MER

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

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Simon Zemui; [2017]
    Nyckelord :Axle steel beams; hardness; Quenching; tempering;

    Sammanfattning : 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. LÄS MER

  7. 5. Development of a heat treatment method to form a duplex microstructure of lower bainite and martensite in AISI 4140 stee

    Master-uppsats, KTH/Materialvetenskap

    Författare :Erik Claesson; [2014]
    Nyckelord :AISI 4140; 326C; 326F; Isothermal heat treatment; Martensite; Bainite; Molten salt; vacuum furnace; gas quenching.;

    Sammanfattning : Research on bainite and martensite structures has indicated that lower bainite needles have a refining effect on the lath martensitic structure. Lower bainte needles partitions prior austenite grains and will consequently have a refining effect on the subsequent formed lath martensite. LÄS MER
