The Extra Flask

Abstract

It seemed quite natural and logical for me to want to address such an informed group about some of the many superalloys developed over the past forty years-but then I realized that most, if not all of them are listed with their compositions and properties in the ASM Metals Handbook, so this subject did not seem promising. At this point I started to think about the many new and important developments in processing techniques that made the melting, casting, and forming of the alloys possible. It seemed to me that the new procedures were, in most every instance, just as important as the new compositions themselves. Without the new techniques, many of the higher strength compositions were difficult, if not impossible to produce by existing procedures. Certainly, vacuum induction melting allowed us to melt and cast the titanium-and aluminum-bearing compositions without incurring the usual oxide and nitride inclusions.
