  1. 1. Insights into wear and deformation of alternative binder hardmetals

    Författare :Lisa Toller-Nordström; Susanne Norgren; Ben Britton; Uppsala universitet; []
    Nyckelord :hardmetal; cemented carbide; alternative binders; steel turning; electron microscopy; electron diffraction; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : This work presents new insights into how hardmetals with alternative binders as well as cobalt based references react to wear and deformation. The main focus has been on hardmetals for steel turning, but also on studying certain fundamental properties of the new binder materials. LÄS MER

    Sammanfattning : The goal of this work is to understand how the wear and deformation mechanisms of hardmetalinserts change when the cobalt binder phase is replaced with a dierent metal or analloy. The focus is on inserts for steel turning. The work presented in this licentiate thesisconsists of the rst steps. LÄS MER
