ABSTRACT:
Cotton-like aggregates (B) including grinding chips from an iron-based metal and a grinding fluid containing oil and water are compression molded for forming a brittle compact (C) having the fibrous grinding chips roughly sheared and excessive water and oil removed therefrom. The brittle compact (C) is crushed for further finely shearing the grinding chips and the resultant grinding chips are mixed with a solidification assistant (D) for producing an iron-based powder material (E) containing the solidification assistant (D).
