  1. 1. An AI approach for quality improvement in heat treatment processing

    University essay from Uppsala universitet/Industriell teknik

    Author : Kruse Gustav; Lotta Åhag; [2022]
    Keywords : Artificial intelligence; heat treatment; mining; steel; smart manufacturing; pipeline; hardness; cooling; quality improvement;

    Abstract : Export of heat treated steel goods has an important impact on the Swedish economy which brings performance demands and expectations on production to keep a competitive market position. Sustainability and efficiency are two important aspects in meeting these demands. READ MORE

  2. 2. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides

    University essay from KTH/Materialvetenskap

    Author : Filip Ivarsson; [2022]
    Keywords : Cemented Carbides; WC Grain Size Distribution; Mechanical Properties; Microstructure Analysis; Hårdmetall; WC Kornstorleksfördelning; Mekaniska Egenskaper; Mikrostruktur Analys;

    Abstract : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this  thesis  aims  to  broaden  the  knowledge  and  answer  whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.

  3. 3. Fatigue Crack Growth Analysis in Python algorithm with Finite Element Methods : Numerical Simulation of Fatigue Crack Growth

    University essay from Karlstads universitet

    Author : Hasan Majid; [2022]
    Keywords : ;

    Abstract : The goal of this thesis was to construct and develop a python-based finite element computer program for the evaluation of fatigue crack growth rate in notched metallic rods. The simulation was done by implementing elastic stress theory and linear elastic fracture mechanics techniques. READ MORE

  4. 4. Verification of elastomer characteristics in electro-mechanical linear actuator

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Rohit Karmungikar; [2022]
    Keywords : ANSYS; Aging; Hyperelastic; MATLAB and Mooney-Rivlin; ANSYS; Åldrande; Hyperelastic; MATLAB och Mooney-Rivlin;

    Abstract : Cascade Drives develops electromechanical actuators using a rack and pinion configuration to achieve a combination of high load and high-speed operation. A patented load distribution mechanism enables the use of multiple pinions on a single rack, resulting in a compact unit with high positional accuracy capable of absorbing shock loads. READ MORE

  5. 5. Air Cooling Analysis of Forged Bearing Steels

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Mattias Sörlander; [2022]
    Keywords : Material; Bearing steel; Cooling;

    Abstract : This thesis work was done in cooperation with Ovako Sweden AB in Hofors to better understand and improve cracking-related problems in bearing ring production and cooling after forging in particular. This goal was achieved by doing a literature search and executing cooling experiments in live production. READ MORE
