Sažetak
This paper describes a modified melt spinning method that provides for production of amorphous ribbons with a nearly constant short-range order. The ribbon structure can be controlled by relevant parameters, and if these parameters are constant, the ribbons produced have approximately the same degree of amorphousness. A detailed investigation proved that it was necessary to control accurately the melting temperature and the surface velocity of the drum on which the quenching is made. The system is computer controlled using specially adapted software. The particular phases during the process of amorphous ribbon production are turned on in accordance with the temperature of the melt. We made a comparative measurement of produced ribbons proving that ribbons produced with the same parameters have approximately the same degree of amorphousness.
