Historical Review of HIP Technology and a Look at New Trends

This paper provides a historical review of the development and the present status of HIP technology, as well as a look at future directions. Thanks to the unique effect of the simultaneous application of isostatic pressure and temperature, a variety of value-added matreials and machinery parts have been developed for commercial use over the past twenty years. As the appli-cation fields have expanded, the HIP apparatus has also been improved to reduce operational costs. Its success in this area has made Japan one of the leading countries in the world. It is expected that the present basic research on HIP processing in various areas will lead to new developments in HIP technology in the near future.
