Computer modelling and tooling design for near net shaped components using hot isostatic pressing

Research output: Contribution to journalArticle



The fundamental principles and assumptions underlying an FEM model are described and this model has been used to predict the final dimensions of shaped components produced by hot isostatically pressing (HIPping) Ti-6Al-4V powder. A CAD module (solidworks) has been used for dimensional calibration, tooling design and engineering drawings. A relatively simple small casing component has been produced and the dimensions compared with those predicted from the modelling. It has been shown that there is agreement within about 2% between the achieved geometries and the predictions for this axial-symmetric cylinder body. The physical bases for some of the local discrepancies are discussed and future developments required for improved modelling are outlined. (c) 2006 Elsevier B.V. All rights reserved.
