Magnetothermal analysis of nanocrystallization of amorphous and relaxations of nanocrystalline materials

摘要

For a few years it has been realized that nanocrystalline phases can be formed during crystal- lization of amorphous alloys annealed isothermally below the crystallization temperature of usual heating experiments. Data of this transformation monitored by the measurement of magnetic susceptibility are presented. A method using a magnetic balance with electronic stabilisation and combined computer facilities is applied. Constant heating and cooling rats as well as isothermal heat treatments are used.
