HIGH-CARBON IRON-BASED AMORPHOUS ALLOY MAKING GOOD USE OF MOLTEN PIG IRON, AND A PRODUCTION METHOD THEREFOR

摘要

The present invention relates to a high-carbon iron-based amorphous alloy making good use of molten pig iron, and to a production method therefor. Provided is a high-carbon iron-based amorphous alloy represented by the general formula FeaCßSi?BxPyCrz, where a, ß, ?, x, y and z respectively represent the atomic percentages of iron (Fe), carbon (C), silicon (Si), boron (B), phosphorus (P) and chromium (Cr), and, where a is concerned, a=100-(ß+?+x+y+z) atomic percent, while ß is 13.5 atomic percent = ß = 17.8 atomic percent, ? is 0.30 atomic percent = ? = 1.50 atomic percent, x is 0.1 atomic percent = x = 4.0 atomic percent, y is 0.8 atomic percent = y = 7.7 atomic percent, and z is 0.1 atomic percent = z = 3.0 atomic percent.
