Specific Time-Temperature Treatment Preparing the Melt for the Amorphous State

Article Preview

Abstract:

Taking into account the concept of the quasi-chemical model of the liquid micro-non-uniform composition and the research made on the physical properties of the Fe-and Co-based melts being crystallized, the unique technology of the melt time-temperature treatment has been developed. Amorphous ribbons produced using this technology require optimal annealing temperatures to be specifically selected. The results of studying nanocrystalline magnetic core’ properties and their structure in the course of annealing at temperatures below and above the optimal ones are presented.
