Liquid Phase Sintering of Fe-Cu-Sn-Pb System

Abstract

In this study the formation of the liquid phase during sintering process of Fe-Cu-Sn-Pb system was investigated. In order to reach this purpose a new material based on iron powder was developed using PM technologies. Additions like copper, tin and lead were added to iron powder and the mixture was sintered in dry hydrogen atmosphere at different temperatures and maintaining time. The liquid phase formed during sintering led to a considerable accurate process and swelling of the sintered compact was observed and studied.
