  1. 1. Melt pool Geometry and Microstructure Characterization in Additively Manufactured WE43 Alloy

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Satya Chaitanya Vaddamanu; [2022]
    Keywords : ;

    Abstract : Mg-RE based alloys have exhibited promising properties in application for biodegradable implants. This work provides a systematic study on the characterization of melt pool geometry and profile for one such alloy, WE43. READ MORE

  3. 2. Sample quality effects of laser cutting : An empirical study on the heat affected zone and the surface quality in laser cut samples

    University essay from KTH/Materialvetenskap

    Author : Emma Bevin; Matilda Björklund; [2020]
    Keywords : Laser cutting; Laser cutting quality; Heat affected zone; Surface quality; Surface angularity; Laserskärning; Laserskärnings-kvalité; Värmepåverkad zon; Ytkvalité; Ytvinkel;

    Abstract : This study has been conducted with the aim to examine the extent of the heat affected zone in order to use laser cutting when making samples for tensile testing. When cutting with a laser the material absorbs heat energy from the laser beams which causes changes in the microstructure. READ MORE

  4. 3. Understanding Effects of Isothermal Heat Treatments on Microstructure of LMD-w Titanium Alloy (Ti-6242) : On solution heat treated microstructure

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Noomi Linder; [2020]
    Keywords : Heat Treatments Isothermal Titanium Alloy Ti-6242 Ti6242 Ti-6Al-2Sn-4Zr-2Mo GKN;

    Abstract : The use and knowledge of additive manufacturing technologies are rapidly growing. It is crucial to understand the processing-structure-property relationship, which is highly discussed when trying to understand the science of a material. One commonly used material in aerospace applications is titanium alloy, lately Ti-6Al-2Sn-4Zr-2Mo (Ti-6242). READ MORE

  5. 4. Assessment of static performance of LKAB´s welded mesh : Laboratory testing and analysis

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Fredrik Eriksson; [2020]
    Keywords : ;

    Abstract : Surface support is an areal support, which is installed on rock excavation surface to prevent bulking of rock mass and retain loose rock fragments. Welded wire mesh is one type of surface support. Literature study indicates that there is a wide range of testing methods on mesh. READ MORE

  6. 5. Evaluation of material properties after laser welding on ductile cast iron

    University essay from KTH/Materialvetenskap

    Author : Olivia Taivalkoski; [2019]
    Keywords : Laser welding; ductile cast iron;

    Abstract : Scania wants to lower the weight of their trucks, including the goal to reduce the carbon dioxide emissions, and one way to do that is to use laser welding instead of fastenings.This bachelor thesis work is about laser welding of ductile cast iron, or spheroidal graphite cast iron or nodular cast iron, to QT-steels and case hardening steel and evaluation of the mechanical properties of the weld.
