IPC: B22F1/00
Filed: 2018-08-24
Abstract: To provide a production method by which a member having unprecedented high hardness and high toughness can be produced by providing a carbon-containing iron alloy material having a harmonic structure.SOLUTION: The production method includes steps of: subjecting a carbon-containing iron alloy powder to a crystal grain refining process on a surface layer portion of the powder so as to prepare a processed powder having a structure including a fine crystal grain structure in the surface layer portion and a coarse crystal grain structure inside the surface layer portion; sintering the processed powder to form a sintered body having a harmonic structure that is a three-dimensional network structure in which coarse crystal grain regions dispersed like dots are encapsulated by the fine crystal grain region; and rapidly cooling the sintered body. Prior to the rapid cooling, the sintered body is heated under such temperature conditions that induce an austenite transformation so as to produce more austenite phases in the fine crystal grain region than in the coarse crystal grain region, and then the sintered body is rapidly cooled to transform the austenite phases into martensite phases so as to obtain a carbon-containing iron alloy material in which more martensite phases are included in the fine crystal grain region than in the coarse crystal grain region.SELECTED DRAWING: Figure 1
