| Zusammenfassung: | According to the present invention, provided is a method for analyzing a steel material comprising: a step of preparing a steel material in which an interphase precipitate is precipitated in a single-phase ferrite base; a step of measuring a size of the interphase precipitate; a step of measuring an arrangement relationship of the interphase precipitate; a step of measuring an orientation between the base and the interphase precipitate; and a step of calculating a precipitation enhancement effect by the interphase precipitate by considering the size of the interphase precipitate, the arrangement relationship of the interphase precipitate, and the orientation between the base and the interphase precipitate. Therefore, the method for analyzing the steel material capable of accurately reflecting a precipitation effect caused by the interphase precipitate can be implemented.
