A bipolar pulse-type hysteresis loop tracer for rare earth based permanent magnets

Strength distributions of laminated FeNi-based metal amorphous nanocomposite ribbons

“…While more work is needed to study the effects of the types of cracks observed on magnetic performance, existing literature suggests that these cracks would increase coercivity and decrease permeability. 34,35 Thus, a TWC subjected to a small stress which develops few distributed cracks may exhibit a minimal change in magnetic performance, but many cracks may significantly influence magnetic properties.…”

“…32,33 While laminated composites are known to mechanically survive some local cracking, it must be noted that cracked magnetic material is associated with localized gaps, which will alter magnetic properties such as effective coercivity and permeability. 34,35…”

“…32,33 While laminated composites are known to mechanically survive some local cracking, it must be noted that cracked magnetic material is associated with localized gaps, which will alter magnetic properties such as effective coercivity and permeability. 34,35 While MANCs in composite form have not been studied in the literature, the tensile response of AMR in composite form has been investigated by Leng and Courtney 36,37 and Li et al 38 Both studies found an increase in ductility and strength by plating an AMR in another ductile metal. However, these benefits were achieved at the expense of volume fraction of AMR with a substantial increase in the amount of high strength ductile material.…”
