1. Continuum modelling of work hardening in precipitation hardened alloys
Sammanfattning : This thesis deals with prediction of macroscopic work hardening in a precipitation hardened alloy. The focus is on the particle contribution. A hierarchical modelling approach is adopted where work hardening in a representative material volume on the microscale is homogenized and used to represent the macroscopic hardening. LÄS MER
2. Wear in cone crusher chambers
Sammanfattning : Cone crushers are widely used in the mining and aggregates industries to reduce the size of blasted rock. A cone crusher consists of a fixed conic liner called concave and inside it a smaller moving liner called mantle. The mantle is suspended on an eccentrically rotating shaft. LÄS MER
3. Deformation Behaviour of Near Fully Pearlitic Railway Steels During Monotonic and Cyclic Loading
Sammanfattning : The main conclusions that could be drawn from the present work are that the deformation behaviour of fully and near fully pearlitic steels is very similar and that a combination of low temperature, prestraining and high deformation rates is critical for the performance. This was shown from microscopy studies, tensile, impact and low cycle fatigue (LCF) testing. LÄS MER

5. Modelling mechanical properties by analysing datasets of commercial alloys
Sammanfattning : Commercial alloys are continuously developed to improve their performance. Therefore it is important to develop new optimisation software, which could be used in development of new materials or in materials selection. In this study the mechanical properties which are important in materials selection in mechanical design are investigated. LÄS MER
