| Abstract | The use of sinter-hardening steel powders combined with furnaces equipped with fast cooling units is a cost effective process allowing the production of parts with high strength and apparent hardness without the use of subsequent heat-treatment. However, the high hardness achieved after sintering makes subsequent machining or sizing operations very difficult. Therefore, it becomes crucial to carefully control the final dimensions of parts. The use of a dilatometer is a powerful tool to better understand the phenomena that occur during sintering and affect the final dimensions of parts. In particular, dilatometry can be used to develop powder mix formulations with an improved dimensional stability. This paper presents the results of dilatometric tests carried out on sinter hardening powders admixed with different types and levels of additives. In particular, the influence of graphite, copper and lubricant grades on the dimensional variation during sintering is presented. The effects of sintering temperature and time on the final dimensions are also discussed. |
