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. Uncertainties in tropical precipitation and radiative feedbacks under climate change
Abstract : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. READ MORE

3. Thermodynamic and kinetic investigation of systems related to lightweight steels
Abstract : Lightweight steels have attracted considerable interest for automobile applications due to the weight reduction without loss of high strength and with retained excellent plasticity. In austenitic Fe-Mn-Al-C steels, the nano-precipitation of the κ-carbide within the austenitic matrix significantly contributes to the increase in yield strength. READ MORE

4. Integrated Experimental and Computational Study of Precipitation in Martensitic Steels
Abstract : Precipitation is a phase transformation process in metallic materials that significantlyaffects properties. The precipitation process that includes nucleation, growth andcoarsening of small particles can be tuned by alloying, deformation, thermal treatment. READ MORE

5. Development of high performance aluminium alloys tailored for powder bed fusion-laser beam
Abstract : The powder bed fusion-laser beam (PBF-LB) process has lately been regarded as a top choice for creating complicated structures which are not possible via conventional manufacturing. Nevertheless, the pace of alloys for PBF-LB has been slower. READ MORE
