Last year the advantage of austempering after high temperature sintering was described. It was shown that, with austempering, a true hardness equivalent to wrought steels is possible. However there is added cost involved with high temperature sintering. Therefore the natural question that evolves is what if you sinter at a conventional sintering temperature of 1120℃ and austemper. This paper describes the tensile properties mat result from sintering at 1120℃ and austempering according to the cycle described in the previous paper. The properties that are obtained are compared with properties that resulted from the high temperature sinter and austemper cycle. Finally, differences in the respective properties are described. Ways to improve the properties are explored.
