Steel Base

Alloy 690 is a 30 wt% chromium base metal with excellent resistance to PWSCC. Alloy 52M (ERNiCr-7A) is weld filler metal that closely matches the composition of Alloy 690 and also exhibits excellent resistance to PWSCC [1]. Alloy 52M is currently used for new nuclear component fabrication and for repair and mitigation of PWSCC in operating nuclear power plants. Unfortunately, industry experience and laboratory testing has shown that Alloy 52M is susceptible to hot cracking when welding over some austenitic stainless steel base material compositions. Currently there is no clear understanding of the specific composition levels that increase the susceptibility to hot cracking. This paper summarizes preliminary results of an EPRI study on hot cracking susceptibility Alloy 52M when welded on a range of austenitic stainless steel samples [2]. The focus of the EPRI study was to identify high risk base metals with compositions that promote hot cracking and provide counter measures to mitigate or lessen the propensity for hot cracking.

The analysis of stacking fault tetrahedra (SFT) in fatigued metals (1,2) is somewhat complicated, due partly to their relatively low density, but principally to the presence of a very high density of dislocations which hides them. In order to overcome this second difficulty, we have used in this work an austenitic stainless steel that deforms in a planar mode and, as expected, examination of the substructure revealed planar arrays of dislocation dipoles rather than the cellular structures which appear both in single and polycrystals of cyclically deformed copper and silver. This more uniform distribution of dislocations allows a better identification of the SFT.The samples were fatigue deformed at the constant total strain amplitude Δε = 0.025 for 5 cycles at three temperatures: 85, 293 and 773 K. One of the samples was tensile strained with a total deformation of 3.5%.
