épületében, 4.52 (Sas Elemér) teremben Evgeniya Kabliman (Light Metals 
Technologies Ranshofen, Center for Low- Emission Transport, Austrian 
Institute of Technology, Ausztria) Modeling of microstructure evolution 
in aluminum alloys during thermomechanical processing Abstract: The 
final properties of materials are strongly influenced by evolution of 
their microstructure. During the production of aluminum semi-products 
the material passes through several processing steps (casting, rolling, 
annealing), each of them seriously affects the microstructure due to 
phase transformations, plastic deformation and restoration processes 
such as recovery, recrystallization and grain growth. In order to 
predict the final properties of materials one has to understand and 
describe the underlying mechanisms of the microstructure evolution such 
as dislocation and grain boundary motion. For this purpose we develop a 
model which is based on evolution of mean dislocation density and 
includes the interaction with microchemistry through the modeling of 
precipitation kinetics. This model is than integrated into a 
finite-element code for simulation of deformation processes for real 
size objects. In present lecture I will talk about modeling of aluminum 
alloys at different length scales, linking of models and validation 
through various experimental techniques. Minden érdeklődőt szívesen 
várunk. A szemeszter szemináriumainak programja megtalálható a
