誘導焼結法による炭素鋼の急速焼結技術の開発 Development of Rapid Sintering Technique on Carbon Steels by the Induction Heating Method
From the purpose of rapid sintering technique within a few minutes, this study was used the green compact of die assembly's lubricant method. Specimen were composited 0.8mass%C-1.5mass%Cu-bal. Fe powders, and used to the high frequency induction heating instrument. By the rapid sintering method, there is very important factor both the removal of adsorbed gas in powder grain surface and accompanied by the diffusion and sintering of each powder. As a result, the isothermal treatment (1223K-90s) when the sintering process in this experiment was a key technology treatment. That is to say, this new sintering method obtaind more radial crushing strength values than that of the conventional furnance process. This method was finished to sinter only 3 minutes, and it's condition was maximum heating time-30s, sintering condition 1523K-60s and isothermal treatment-90s holding only.
