Title: Report on the FY18 creep rupture and creep-fatigue tests on the first commercial heat of Alloy 709

Abstract

Creep, fatigue and creep-fatigue tests were performed on the Carlson plate of Alloy 709 (ID 58776). The plate, which is the first of the commercial heats tested, was divided into several sections, each undergoing different processing conditions. The effects of processing method and solution annealing temperature were studied in FY18 to inform best procedures for the second heat. The solution annealing temperature of 1050°C was found to be unacceptable due to the grain size being smaller than allowed by the specifications, as well as generally having poor creep properties. Both argon oxygen decarburization AOD and electro-slag remeltin ESR were found to have desirable properties, and the homogenization heat treatment was found to not significantly improve the mechanical properties.
