IPM - Diffusion and Thermodynamics Group

Introduction

The activities of the group are concentrated on the investigation of volume diffusion and diffusion along high-diffusivity paths, on chemical diffusion under concentration gradients in multiphase materials and in weldments, on measurements of thermodynamic properties of alloys in solid state and calculation of thermodynamic characteristics and on investigation of diffusion of gasses in solids. Diffusion processes are studied close to surface of chosen Ni alloys for heat exchange systems of nucelar reactors expposed to molten cooling media (halide salts).

Following topics have been studied in last five years

Bulk and grain boundary diffusion in Mg alloys both with and without ceramic reinforcement.
Bulk and grain boundary diffusion in amorphous FINEMET and NANOPERM - type alloys.
Bulk and grain boundary diffusion in nickel.
Diffusion of hydrogen in Mg, Mg-xNi and Mg-xNi-yX alloys with the third element X (X = Zn, Ga, In, Si, Ge a Sn).
Changes of local chemical composition are studied in chosen Ni alloys exposed to molted halide salts.
Iron diffusion in Fe-based bulk metallic glasses.
