Abstract
The conventional dilatometric technique is applied to study the thermal expansion of the metallic glass Co63(FeNi)10V2Si10B15 with cylindrical samples rolled from ribbon. The heatingrate effect on expansion and differential thermal analysis (DTA) is investigated. The non-linear region of the temperature variation curves of relative elongation all show a broad peak and a distinct peak which correspond to those in DTA. The broad peak in DTA resolves into two peaks: the first one is associated with the glass transition which is interpreted as a quasi-first-order transformation. On comparing with X-ray diffraction analysis, the crystallization is determined to be a two-stage process in which Co(4F) precipitation is a controlling factor.
