Abstract
A structure of a two-phase steel is controlled by subjecting a steel containing C: 0.05-0.80 mass % to a strain work in a true strain quantity of not less than 0.1 at a temperature zone of α-phase or γ-phase and then applying a magnetic field of 0.1-20T thereto within a temperature range forming a two-phase zone of α-phase and γ-phase.
Claims3
A method for controlling a structure of a two-phase steel, characterized in that a steel containing C:
- 0.05-0.80 mass % is subjected to a work forming a true strain of not less than 0.1 at a temperature zone of α-phase or γ-phase and then a magnetic field of 0.1-20T is applied thereto within a temperature range forming a two-phase zone of α-phase and γ-phase.
