| Poznata melt-spinning metoda poboljšana je korištenjem posebnog kompjuterskog programa, koji je omogućio kontrolisanje vise relevantnih parametara u toku proizvodnje amorfnih traka. Dobivene su trake sa visokim stepenom amorfnosti, koje su bile reproducibilne. Njihov kvalitet je kontrolisan kalorimetrijskim metodama Na nekonzerviranim uzorcima ispitivani su procesi strukturne relaksacije.Mjerenje magnetske susceptibilnost na konzerviranim uzorima u širokom intervalu temperatura identifikovala su postojanje ranih metastabilnih stanja.. |
A special computer program was designed to enable a good an and constant control of a few relevant parameters in the production of amorphos ribbons by use of the melt spinning method. The ribbons obtained were reproducible with a high degree of amorpousness. Their quality was investigated by calorimetric methods. Unconserved samples were used for investigation of relaxation processes. Measurements of magnetic susceptibility performed on as-quenched samples in a wide temperature range have identified the presence of early metastable states in those samples. |
