New Findings in Materials Science Described from Technical University (Influence of ball milling on atomic structure and magnetic properties of Co40Fe22Ta8B30 glassy alloy)

By a News Reporter-Staff News Editor at Journal of Technology -- New research on Materials Science is the subject of a report. According to news reporting out of Dresden, Germany, by VerticalNews editors, research stated, "The influence of ball milling on the atomic structure and magnetic properties of the Co40Fe22Ta8B30 metallic glass with a high thermal stability and excellent soft magnetic properties has been investigated. After 14 h of milling, the obtained powders were found to consist mainly of an amorphous phase and a small fraction of the (Co,Fe)(21)Ta(2)B(6)nanocrystals."

Our news journalists obtained a quote from the research from Technical University, "The changes in the reduced pair correlation functions suggest noticeable changes in the atomic structure of the amorphous upon ball milling. Furthermore, it has been shown that milling is accompanied by introduction of compressive and dilatational sites in the glassy phase and increasing the fluctuation of the atomic-level hydrostatic stress without affecting the coordination number of the nearest neighbors."

According to the news editors, the research concluded: "Ball milling has decreased the thermal stability and significantly affected the magnetic properties through increasing the saturation magnetization, Curie temperature of the amorphous phase and coercivity."
