   Sammanfattning : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. LÄS MER

3. 2. Compressive stresses in cemented carbide

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

   Författare :Elias Nyrot; [2013]
   Nyckelord :;

   Sammanfattning : This master thesis work aims towards gaining a deeper understanding of residualstresses in cemented carbide rock drill inserts. Compressive stresses are wanted inthe surface material since they prevent crack growth and wear of the material andthis work is part of the development of better and longer lasting inserts. LÄS MER
