Abstract
From a metal forming perspective, warm forming technologies can be used to reclaim the shape and functionality of worn engineering steel parts such as case-hardened geared components. Since forming temperatures are beneath the material-transformation temperature, no loss in hardness is expected and a new heat treatment can be omitted. In order to determine a process window for reclaiming geared components, upsetting tests were carried out on case-hardened workpieces made of AISI 5115. The workpieces were heated to between 700 °C and 900 °C by induction or furnace heating and upset to a true strain between 0.1 and 0.4. The upset workpieces were cooled in two media, air and water, and metallographically investigated. The combination of 900 °C furnace heating, upsetting (φh = 0.4) and quenching led to an increase of 60% in case-hardening depth. This procedure can be used for reclaiming geared components by means of forming technology.
