Description

Nickel base alloys containing 30 pc chromium (NC30Fe, Inconel 690) are increasingly present in the nuclear industry. These alloys are welded by using 52 (TIG of flux wire) of 152 (coated electrode) filler alloy, but these grades are more sensitive to fillers containing 15 pc chromium to ductility dip cracking or DDC. In this article, the authors first describe the mechanisms and governing parameters of DDC by focussing on the 52 alloy and its derivatives. They discuss how to struggle against DDC. Then, they report some experimental results obtained by AREVA during tensile tests performed at high temperature, and during different characterization and technological tests (Programmable Velocity Range or PVR test, circular groove test). They discuss the correlation between the PVR test and metallurgical studies
