Abstract
This study of rapid sinteing method within a few minutes is to investigate under nitrogen atmosphere. Specimens were composited 0.8mass%C-1.5mass%Cu-bal.Fe powders and used by the high frequency induction heating instrument. In this case, it was important to release an adsorbed gas in iron powder particle surface. The product of decarburized layer on specimen surface was a problem because of reduce of mechanical properties. As a result, it was possible to keep about 40μm at a minimum as the decarburized layer when the constant sintering condition (1523 K-30s, LT 1323 K-60s and heating rate 10 K/s). This method was finished to sinter only 3.5 minites, and the radial crushing strength (R.C.S) was obtained almost same value compared to conventional furnace method.
