ALLOY, MAGNETIC CORE AND PROCESS FOR THE PRODUCTION OF A TAPE FROM AN ALLOY |
| 摘要 |
An alloy is provided which consists of Fe100-a-b-c-d-x-y-zCuaNbbMcTdSixByZz and up to 1 at % impurities, M being one or more of the elements Mo, Ta and Zr, T being one or more of the elements V, Mn, Cr, Co and Ni, Z being one or more of the elements C, P and Ge, 0 at %≦a<1.5 at %, 0 at %≦b<2 at %, 0 at %≦(b+c)<2 at %, 0 at %≦d<5 at %, 10 at %<x<18 at %, 5 at %<y<11 at % and 0 at %≦z<2 at %. The alloy is configured in tape form and has a nanocrystalline structure in which at least 50 vol % of the grains have an average size of less than 100 nm, a hysteresis loop with a central linear region, a remanence ratio Jr/Js of <0.1 and a coercive field strength Hc to anisotropic field strength Ha ratio of <10%. |

1. An alloy, consisting of Fe100-a-b-c-d-x-y-zCuaNbbMcTdSixByZz and up to 1 at % impurities, wherein M is one or more of the elements Mo, Ta or Zr, T is one or more of the elements V, Mn, Cr, Co or Ni, Z is one or more of the elements C, P or Ge, and wherein 0 at %≦a<1.5 at %, 0 at %≦b<2 at %, 0 at %≦(b+c)<2 at %, 0 at %≦d<5 at %, 10 at %<x<18 at %, 5 at %<y<11 at % and 0 at %≦z<2 at %, wherein the alloy is configured in tape form, wherein the alloy has a nanocrystalline structure in which at least 50% vol of the grains have an average size of less than 100 nm, and wherein the saturation polarization (Js) of the alloy is at least 1.21 T. |
