Abstract

A network based approach to model the thermal history of a billet generated by the Osprey preform process is described. Test cases have been completed to illustrate the technique which suggest that the method can be used successfully to predict preform temperature histories during build-up. The test cases confirm that heat removal from the billet outer diameter is most important for long billets while heat removal from the end is a dominant convective path for larger diameter sections. The prediction also illustrates the need for a cooler spray to assure successful deposition in the case of long smaller diameter sections.
