The present paper deals with in-situ and non-destructive characterization of the vacuum carburizing process. For this purpose, the unique laboratory device was set up, that enables measuring the carbon diffusion during vacuum carburizing process by electrical resistance measurements. We determined the kinetics of the process and the microstructural changes during carburizing of plain carbon and corrosion resistant stainless steel (N360 iso extra).

COBISS.SI-ID: 14464022Recrystallization and grain growth of a cold deformed Au-La alloy have been studied with optical and electron microscopy as well as microhardness measurements. Depending on the experimental results a recrystallization map that gives the correlation between degree of deformation, annealing temperature and hardness has been constructed

COBISS.SI-ID: 14463510The present paper deals with review of basic fundamentals of shape memory alloys accompanied with our experimental results. Shape memory wires were trained under constant stress in order to introduce a uniaxial shape memory effect by a thermomechanical treatment. These investigations were carried out on three different alloy systems (NiTi, NiTiW and CuAlNi) with different microstructures. The influence of the microstructure on development and stability of the intrinsic two-way shape memory effect has been discussed. Furthermore, this work deals with the production of thin specimens of shape memory alloys by melt-spinning and splat-cooling, the training procedure and their characterization with respect to microstructure and functional properties.
