Abstract
Relaxation processes in Fe 85 B 15 and Fe 75 B 25 metal glasses after pulse laser thermocycling treatment were investigated by means of electroresistance temperature dependence measurement and X-ray powder diffraction method. It has been shown that the laser thermocycling under precrystallization regimes leads to a shift of a glass temperature stability interval toward higher temperatures. Such a shift is due to local topology and composition changes in glasses, which take place after short-term laser heating resulting in formation of clusters with strong thermally stable covalent bonds.
