Abstract
The effects of silicon additions on the microstructures, mechanical properties, and hardenability of powder metallurgy (PM) alloy systems have been investigated. It has been demonstrated that the addition of silicon can increase strength in both the sintered and heat-treated conditions. In the sintered condition silicon strengthens the ferrite of the pearlitic microstructure by solid-solution hardening. The heat-treated properties of various silicon-containing alloy systems were examined and the hardenability was compared for various alloys by means of microindentation-hardness measurements. The effectiveness of accelerated cooling during sintering on the sinter-hardening response of silicon-containing alloys was demonstrated. The addition of silicon to high-carbon (>0.80 w/o) PM steels suppresses the formation of grain-boundary carbides, which permits the use of carbon levels that are significantly higher than those commonly used for commercial PM applications.
