  1. 1. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER

  3. 2. Cryogenic properties of additive manufactured austenitic stainless steels for space applications

    Master-uppsats, Luleå tekniska universitet/Materialvetenskap

    Författare :Patricio Piantanida; [2023]
    Nyckelord :austenitic stainless steel; additive manufacturing; cryogenic;

    Sammanfattning : The mechanical properties of three austenitic stainless steel alloys, namely 21-6-9, 316L and a modifed 316, fabricated via laser powder bed fusion, have been studied. From the results previously obtained through tensile tests at room and cryogenic temperatures, their strength and ductility were compared against similar conventionally processed materials. LÄS MER

  4. 3. Optimizing Induction Heating for Manganese Steel for Induction Assisted Machining

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Ravshan Yakupov; [2023]
    Nyckelord :induction assistive machining; induction assisted machining; manganese steel; preheating; induction coil; reinforced material; Technology and Engineering;

    Sammanfattning : The main factors for usage of Induction assisted machining of Manganese steel were identified in this project. The testing environment to evaluate performance of the high frequency coils for turning and milling was created. The characteristics of the material that we are working with were measured. LÄS MER

  5. 4. Mechanical design guidelines and criteria for mooring components in wave energy devices : Finding the optimum chain and shackle parameters

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

    Författare :Arvin Modiri; [2022]
    Nyckelord :Chain; shackle; finite element method; wave energy converter; WEC; Kedja; kätting; schackel; finita element metoden; vågkraftverk;

    Sammanfattning : Obtaining the perfect renewable energy source is one of the most important questions of our lifetime. One renewable energy source that could be of interest in this question because of the characteristics of the power that could be extracted from it is wave energy. LÄS MER

  7. 5. Reduktion av injekteringstid : cementbruks reologiska egenskaper och dess effekt vid injektering

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Wilhelm Åberg; [2022]
    Nyckelord :Västlänken; injektering; cement; reologi; rheometer;

    Sammanfattning : Tunneldrivning är tidskrävande med varierande komplexitet från projekt till projekt, där en betydande del av sprängcykeln innefattar att låta injektering härda. Detta är tid där tunneldrivandet står stilla. Ifall denna tid skulle kunna reduceras skulle entreprenörer kunna spara in resurser genom att kunna spränga tidigare. LÄS MER
