摘要:
Disclosed is an amorphous, ductile brazing foil with a composition consisting essentially of NirestCraBbPcSid with 2 atomic percent ≦a≦30 atomic percent; 0.5 atomic percent ≦b≦14 atomic percent; 2 atomic percent ≦c≦20 atomic percent; 0 atomic percent ≦d≦14 atomic percent; incidental impurities ≦0.5 atomic percent; rest Ni, where c>b>c/15 and 10 atomic percent ≦b+c+d≦25 atomic percent. Also disclosed is amorphous, ductile Ni-based brazing foil having a composition consisting essentially of NirestCraBbPcSidCeXfYg wherein a, b, c, d, e, f, and g are numbers such that 2 atomic percent ≦a≦30 atomic percent; 0.5 atomic percent ≦b≦14 atomic percent; 2 atomic percent ≦c≦20 atomic percent; 0 atomic percent ≦d≦14 atomic percent; 0 atomic percent ≦e≦5 atomic percent; 0 atomic percent ≦f≦5 atomic percent; 0 atomic percent ≦g≦20 atomic percent; wherein incidental impurities are present, if at all, in amounts ≦0.5 atomic percent; wherein rest indicates that the balance of the composition is Ni; wherein c>b>c/15; wherein 10 atomic percent ≦b+c+d≦25 atomic percent, wherein X is one or more of the elements Mo, Nb, Ta, W and Cu; and wherein Y is one or both of the elements Fe and Co. Also disclosed are methods for making and using these brazing foils, and brazed objects produced therefrom.
