Our studies on the sintered iron-base alloys for machine parts are still going on. This is a report covering the properties of iron-copper sintered alloys and a discussion on several problems as follows.:
1) Effects of the iron powder distribution on dimensional changes of sintered compacts.
2) Effects of the copper content on the properties of the sintered compacts.
3) On the properties of sintered compacts made by a repressing method.
4) On the properties of sintered compacts using electrolytic or reduced iron powders
5) On the precipitation-hardening of sintered compacts.
6) On the gas-carburization of sintered compacts.
