METASTABLE AUSTENITIC FORMING OF HIGH STRENGTH PRESSURE VESSELS.

Abstract

Detailed analysis of the effects of the various processing parameters employed during Phase I effort was completed. Most information was obtained from the full factorial experiment of the 18NiCoMo (300) maraging steel, where parametric and non-parametric analyses were carried out. From these analyses, an optimum combination of processing parameters was derived, and incorporated in the processing schedule of the intermediate size cylindrical test specimen. All necessary forgings in 18 NiCoMo (300) maraging steel and tooling for fabrication were obtained and two 14.5 in. diameter cylindrical test bottles were spun to verify the results obtained during Phase I. Effort was made in evaluating the backup approach to effect closure of the aft end by a shrinking operation. (Author)
