Abstract Scope |
FINEMET ribbons are an emerging advanced material with potential uses in high-efficiency electronics systems due to their unique and advantageous magnetic properties. Properties such as magnetic coercivity, anisotropy, and relative permeability can be controlled in these materials by strain annealing processes. However, Fe-based FINEMET-type ribbons are susceptible to severe embrittlement during low temperature annealing. The objective of the present study aims to understand or elucidate the embrittlement mechanism in FINEMET ribbons through characterization of mechanical properties extracted from uniaxial tension tests and thermomechanical analysis (TMA). Moreover, microscopy is performed to characterize inherent defects, such as cracks and pits, created during ribbon melt-spinning synthesis to better understand materials behavior for the design of a strain annealing system. |
