1. Strain Gradient Plasticity Modelling of Precipitation Strengthening
Abstract : The introduction of particles and precipitates into a matrix material results in strengthening effects. The two main mechanisms involved in this matter are referred to as Orowan and shearing. To numerically study this phenomenon is the motivation to the research done, which is presented here in this thesis. READ MORE

2. Creep modelling of particle strengthened steels
Abstract : Materials to be used in thermal power plants have to resist creep deformation for time periods up to 30 years. The role of alloying elements for creep strength of 9-12% Cr steels is analysed. The creep strength in these steels relies on minor additions of alloying elements. READ MORE

3. Control of particles codeposition and strengthening mechanisms in nickel based nanocomposite coatings
Abstract : Surface durability is a key factor in the service life of components. Depending on the aggressiveness of the environment, surface deterioration by wear or corrosion leads to failure of the bulk material and eventually to the loss of functionality of the component. READ MORE
