Abstract

PURPOSE: To enhance the amorphism forming capacity and thermal stability of an amorphous alloy for a transformer iron core by converting the alloy into an Fe- Si-B-C amorphous alloy having a specified composition.
CONSTITUTION: This amorphous alloy for a transformer iron core has a composition represented by formula I (where a+b+c+d=1, b=0.02W0.08, c=0.08W0.17 and d=0.01W0,08). This alloy is more easily made amorphous as compared to an Fe-B-C alloy, and it is superior to the Fe-B-C alloy in thermal stability. This alloy has a higher crystallization temp., undergoes a much smaller change in the coercive force with the passage of time, e.g., at 140°C, and is thermally stable. On the othr hand, the saturation magnetic flux density is hardly lowered, and the addition of Si results in enhanced exciting characteristics, so this alloy is advantageous as a transformer iron core material.
