Abstract:

Background/aims: In a European Union supported project, the idea that the sintering window for a tool steel, i.e., temperature region where full density is reached with no distortion and a sound microstructure, corresponding to a 3-phase region, austenite + carbide + liquid, of the multicomponent phase diagram, has been validated and exploited. An additional objective was to achieve sintering to full density as close as possible to 1150 degrees C, the current limit for continuous sintering furnaces.
