Application of hot Isostatic Pressing to Aircraft Gas Turbines
Rising material costs and the requirement for improved material capabilities has led aircraft turbine engine designers and materials engineers to explore new technologies for solutions to these economic and performance related problems. Such a technology is hot isostatic pressing (HIP) which, in the 1970s, has gained increased use in materials processing for current and future engine models. This paper examines the background which led to the use of HIP, reviews equipment and processing as applied to gas turbine components, and then discusses specific applications of this area of high pressure technology.
