The aim of this book is to provide an introduction to the increasingly exploited technology of Hot Isostatic Pressing (HIPping). It is intended for two audiences. Firstly, the manufacturing or design engineer who may not have a materials science background, but who needs to develop an appreciation of the scope of the HIPping process. Secondly, the engineering or materials undergraduate who needs to understand how HIPping as a modern manufacturing method can offer potential improvements to material properties relative to more conventional techniques.
