摘要： PURPOSE: To obtain an alloy superior in mechanical strength and corrosion resistance, by cooling rapidly at a specified rate from molten state, an Fe base alloy contg. respectively prescribed ratios of N, Cr or/and Mo, and ≥ one kind among S, C, Si, P, and solidifying it.
CONSTITUTION: The Fe-base alloy contg. by atomic %, 0.01W20 N, 1W40 Cr or/ and Mo, 7W30 one kind or more of B, C, Si and P being semimetal element, further 0.1W15 the following secondary elements is prepared. Said secondary element is ≥one kind among Ti, Zr, V, Nb, W, Mo, Mn, Cu, Ag, Al. Next, the Fe base alloy is cooled rapidly from molten state to 300°C at ≥1,000°C/sec rate and solidified. As the result, alloy favorable as a material used for apparatus, industrial chemical plant, operated in air, sea water or oxidizing atmosphere, etc. and especially required with resistances for general corrosion, stress corrosion, pitting corrosion, etc. is obtd.

摘要： 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=0.02-0.08, c=0.08-0.17 and d=0.01-0,08). 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 deg.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.
