  1. 1. 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.

    Abstract : Intresset för den här studien har byggts på genom åren. Barn och unga har alltid engagerat mig och mitt tidigare arbete som lärare och förskolelärare har gett mig god insikt i barns lekutveckling och lärande. READ MORE

  4. 3. Reliable Carburization of AISI H13 Steel : The Impact of Preoxidation

    University essay from KTH/Materialvetenskap

    Author : Martin Palm; [2020]
    Keywords : Preoxidation; Case hardening; Uddeholm Orvar® Superior; Passive oxide layers; Iron oxides; Carbon adsorption;

    Abstract : Case hardened Uddeholm Orvar® Superior (Orvar) has the potential to replace currently used materials in shafts inside transmissions, which would lower the overall weight and thus result in lower fuel consumption while maintaining the necessary mechanical properties. However, previous studies have failed to reliably carburize the steel during the case hardening process. READ MORE

  5. 4. Analysis of market and requirements of plasticizers for flexible PVC - With a focus on Perstorp’s non-phthalate plasticizer Pevalen

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lisa Bywall; Sofie Cederlund; [2020]
    Keywords : PVC; plasticizer; plasticiser; industry; flexible PVC; polyvinylchloride; vinyl; flooring; chemical engineering; kemiteknik; Chemistry;

    Abstract : Flexible Polyvinyl chloride (PVC) is a plastic material commonly used in today’s society and a fundamental material for a lot of sectors. It has advantages over other polymers such as energy-efficient production, flame retardancy, durability and cost-effective. READ MORE

  6. 5. Design and Implementation of Partial Firmware Upgrade

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Silu Sun; [2019]
    Keywords : Device Firmware Upgrade; Microcontroller; Bluetooth Low Energy; Flash Memory; Wear Leveling; Enhet Firmware-uppgradering; Mikrokontroller; Bluetooth Low Energy; Flash-minne; Slitstyrka;

    Abstract : Device Firmware Upgrade (DFU) is now widely used on PC and smartphones for users to enjoy the latest applications. The project is derived from the new device of Yohoo and the firmware embedded in the system. This system can guide users on how to breathe through multiple sensory effects to reduce the harm from excessive stress. READ MORE
