Abstract
This report explains the history of the developments of the ferrous sintered structual parts by illustrating the progress of their production technology in Japan. The production technology includes the production equipment and the iron powders, in addition to compacting and sintering. Their progress resulted in the improvement of the quality and mechanical property of sintered parts and the expansion of their application in the market. The production of the ferrous sintered structural parts started with the introduction of the foreign technology, but, since 1965, the domestic technology has been fostered and the 1970s have seen a significant expansion of the sintered parts markets through the developments of the technology by our own. In the 1980s Japanese production technology of sintered parts has reached the leading position in the world. In the future, we will be able to expect more expanding and hopeful market for those sintered parts by achieving the revolution of their production technology.
