  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. Machine Learning Methods for Segmentation of Complex Metal Microstructure Features

    Master-uppsats, KTH/Materialvetenskap

    Författare :Daniel Fredriksson; [2022]
    Nyckelord :Machine learning; Metallography; Automatic segmentation; Complex microstructures; Random Forest classifier.; Maskininlärning; Metallografi; Automatisk segmentering; Komplex mikrostruktur; Random Forest klassificerare;

    Sammanfattning : Machine learning is a growing topic with possibilities that seems endless with growing areas of applications. The field of metallography today is highly dependent on the operators’ knowledge and technical equipment to perform segmentation and analysis of the microstructure. Having expert dependents is both costly and very time-consuming. LÄS MER

  4. 3. Optimization of adaptive control for spot welding

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Felix Lindblom; [2021]
    Nyckelord :;

    Sammanfattning : In December 2015 Scania Oskarshamn started production in their new facility for the body in white (BiW) production. Heat capacity control (HCC) is used to control the RSW process for all the welding robots in this facility for BiW at Scania Oskarshamn. LÄS MER

  5. 4. Treatment of a Liquid Al-Si Alloy : Quality Control and Comparison of Two Melt Degassing Processes

    Magister-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Badreddin Radwan; [2020]
    Nyckelord :Dissolved Hydrogen; Degassing; Porosity; Grain Refinement; Eutectic Modification; Fluidity; Metallography; Thermal Analysis.;

    Sammanfattning : Products manufactured by aluminium casting have become very popular and already replaced many parts that were once produced by iron and steel casting. This trends upwards especially in the automotive industry as it has become extremely important to reduce vehicle weight due to environmental requirements and economical aspects. LÄS MER

  7. 5. Image Analysis Methods For Additive Manufacturing Applications

    Master-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Författare :Jayanth Ramakrishna Yogendra; [2020]
    Nyckelord :Additive Manufacturing; Image Analysis; ImageJ; MIPAR; Superalloys;

    Sammanfattning : There is an upsurge of research interest on Ni-based superalloys additively manufactured (AM) in aerospace sectors. However, achieving the accuracy and quality of the AM part is a challenging task because it is a process of adding material layer by layer with different process parameters. LÄS MER
