摘要
PROBLEM TO BE SOLVED: To provide a production method for producing an Fe-group nano-crystal alloy capable of suppressing coarsening suitable for a mass production step.;SOLUTION: The method for producing the Fe-group nano-crystal alloy includes: a first heating step P1 of heating an alloy composition at a first temperature rising rate or a temperature rising rate that can be approximated by the first temperature rising rate; and a second heating step P2 of heating the alloy composition at a second temperature rising rate of 30°C per minute or longer that is larger than the first temperature rising rate. The second heating step P2 is a step of heating an alloy composition over a heating range including a first peak being a heating range that is at least 70% or more of a first temperature range between a first crystallization start temperature and a first crystallization end temperature.;COPYRIGHT: (C)2012,JPO&INPIT
