MAGNETIC CORE, METHOD AND DEVICE FOR ITS PRODUCTION AND USE OF SUCH A MAGNETIC CORE |
| 摘要 |
A magnetic core, such as for an interphase transformer, made of a nanocrystalline alloy, which consists of;Fe100-a-b-c-d-x-y-zCuaNbbMcTdSixByZz and up to 1 at. % of impurities, whereby M is one or more of the elements Mo, Ta or Zr; T is one or more of the elements V, Cr, Co or Ni; and Z is one or more of the elements C, P or Ge, and

1. A magnetic core comprising a nanocrystalline alloy, which consists of Fe100-a-b-c-d-x-y-zCuaNbbMcTdSixByZz and up to 1 at. % of impurities, whereby M is one or more of the elements Mo, Ta or Zr; T is one or more of the elements V, Cr, Co or Ni; and Z is one or more of the elements C, P or Ge, and
0 at. %≦a<1.5 at. %, 0 at. %≦b<4 at. %, 0 at. %≦c<4 at. %, 0 at. %≦d<5 at. %, 12 at. %<x<18 at. %, 5 at. %<y<12 at. %, and 0 at. %≦z<2 at. %,wherein the magnetic core has a saturation magnetostriction of less than 2 ppm and a permeability of between 100 and 1,500, and wherein the alloy has been exposed to a heat treatment at a heat-treatment temperature of between 450 and 750° C. under a tensile stress of between 30 and 500 MPa.
