The heat treatment processing of powder metal (PM) materials like Astaloy requires four steps -- de-waxing, HT
sintering, carburizing and surface hardening -- which are usually achieved in dedicated, atmospheric furnaces for
sintering and heat treat, respectively, leading to intermediate handling operations and repeated heating and cooling cycles. This paper presents the concept of the multi-purpose batch vacuum furnace, one that is able to realize all of these steps in one unique cycle. The multiple benefits brought by this technology are summarized here, the main goal being to use this technology to manufacture high-load transmission gears in PM materials.
