1. Carbon Effect on Mechanical Properties in Austenitic Steels - A DFT-based Study
Sammanfattning : To study the effect of carbon interstitials in austenitic steels on plastic deformation mechanisms is the main goal of the present thesis. Using first-principlesmethods, the generalized stacking fault energy (GSFE) of C-alloyed γ-Fe is firstcalculated. The GSFE curve includes several prominent stacking fault energiesthat are fundamental for, e. LÄS MER
2. Defects in Austenitic Steels and Hard Metals - A DFT-based Study
Sammanfattning : Materials are never 100% pure due to the limitation of purification method or manufacturing process. Nor are they perfect, especially under deformation. The present work aims to explore different roles played by the defects in austenitic steels and hard metals. LÄS MER
