Use of an amorpheus Fe-Co based alloy for a surveillance system based on mechanical resonance

摘要

An amorphous, magnetostrictive alloy has the general formula:- (Fe1-a-bCoaNib)100-x-y-zMxSiyBz where M is one or more element from groups IV-VI including C and P, 0.24 a 0.9, 0 b 5, 0 x 5, 0 y 12, 1 z 20, x+y 0.5, 0.25 a+b 0.9, 12 x+y+z 28.
