Abstract (en)

[origin: WO8803699A1] A glassy metal alloy has a value of magnetostriction near-zero and the composition CoaFebNicMdBeSif, where ''a'' ranges from about 65.5 to 70.5 atom percent, ''b'' ranges from about 3.8 to 4.5 atom percent, ''c'' ranges from about 0 to 3 atom percent, ''d'' ranges from about 1 to about 2 atom percent, ''e'' ranges from about 10 to about 12 atom percent and ''f'' ranges from about 14 to 15 atom percent when M is selected from vanadium, chromium, molybdenum, niobium and tungsten, when M is manganese, ''a'' ranges from about 68.0 to 70.0 atom percent, ''b'' ranges from about 2.5 to 4.0 atom percent, ''c'' ranges from 0 to 3 atom percent, ''d'' ranges from 1 to about 4 atom percent, ''e'' ranges from about 10 to 12 atom percent and ''f'' ranges from about 14 to about 15 atom percent. The alloy has a saturation magnetostriction value ranging from about -1x10<-6> to +1x10<-6>, a saturation induction ranging from about 0.65 to about 0.80 Tesla and a Curie temperature ranging from about 245 to 310 DEG C.
