temperature profile increases the sensitivity by about two orders of magnitude and allows<br />
the separation of reversible and irreversible processes.<br />
The methods have been used to investigate transformations of amorphous alloys before<br />
crystallization. Results obtained for Fe 80 Cr 5 B 15 are depicted in Fig 3. There are visible<br />
changes in mechanical behavior of the material (trace DIL) associated with magnetic and<br />
structural transitions.<br />
The mentioned methods together with the newly developed high heating-rate differential<br />
thermal analysis (DTA) (see Annual Report 2006), allow to get comprehensive<br />
information about kinetics of the devitrification processes. Methods are applied in the<br />
research program on metastable alloys as multicomponents bulk alloys, in collaboration<br />
with the Technical University of Koszalin and Budapest University of Technology and<br />
Economics. Dilatometric measurement with DSC is promising in the investigation of Albased<br />
bulk amorphous alloys that are produced in our institute.<br />
