The present diploma thesis deals with warm forming as a new concept in the sizing process of powder metallurgical components. Using warm forming instead of cold sizing should increase global and local densification as well as the formability of the material and reduce pressing force. In support of this theory an experimental concept including seven sets of experiments is planned and conducted. It is shown that the usefulness of warm sizing is dependent on a specific temperature limit which decreases by increasing natural strain. Compared with cold sizing a higher global density with the same pressing force or a reduced pressing force with the same density data can be achieved above this specific temperature. Local surface densification can be accomplished by using induction heating. However by using the contact from component and die the required temperature gradient in the sample is not achievable with the applied test set-up. Moreover by using warm sizing the mould filling increases, pressing different preforms to the same end-product is enabled and complex components are manufacturable. Because of its process-orientation and dependency on various factors that will be further illustrated in this thesis, an ideal temperature range for component and die does not exist.
