  3. 2. The Influence of Hardness and Retained Austenite on the Fatigue Limit after Shot Peening

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Erik Björklund; [2014]
    Nyckelord :shot peening;

    Sammanfattning : This thesis was performed at Scania CV AB and aimed to optimize the effect of shot peening in order to increase the bending fatigue limit of planetary gears. In this project three parameters affecting the performance of the shot peening were examined in more detail, specifically the hardness of the shot peening media, the hardness of the material and the amount retained austenite.
