The need to cut costs has in recent years led not only to the development of new materials but also to the further development of economic manufacturing processes like advanced casting technology. Advances in casting technology could lead to increased use of castings for the manufacture of vital aircraft components, which in turn leads to reduced cost. Castings are favourable in terms of cost and weight and offer the possibility of combining into one casting a whole number of material-intensive machining and sheet-metal parts which were previously joined by riveting at high cost. Moreover, the process affords the design engineer greater freedom of design. It should be noted that the design should be made suitable for casting, i.e. the design engineer and foundry should get in touch as early as possible during component development. Only thus will it be possible to make maximum use of all the advantages of the process. So far, the lack of confidence of design and stress engineers in casting has stood in the way of a more widespread use of castings for primary structures. However, today there are precise and reliable data concerning castings available. They are collected in this Handbook on Advanced Casting to aid engineers in the application of cost-saving castings.
