A paper published in 2004 described the advantages of austempering after a high temperature sintering process. One disadvantage is the increased cost involved with high temperature sinter cycles. This paper describes the tensile properties that result from sintering at a conventional sinter temperature (1120°C) and austempering according to the cycle describe in a previous paper. The properties that are obtained are compared with the properties that result from high temperature sinter and austemper cycle.
Most parts fabricators do not understand the importance of a quality sinter to provide improved ductility and toughness for tomorrow’s markets. As a result, the potential for growth markets for quality parts has seldom been exploited. Today the main emphasis is still on cost reduction, rather than quality.
