Abstract

A process of producing a NiCrFe alloy having a high resistance to stress corrosion cracking comprises heating a NiCrFe alloy to a temperature sufficient to enable the carbon present in the alloy body in the form of carbide deposits to enter into solution, rapidly cooling the alloy body, and heating the cooled body to a temperature between 1100 to 1500/sup 0/F for about 1 to 30 hours.

Thermally activated dislocation creep model for primary water stress corrosion cracking of NiCrFe alloys

Conference Hall, Jr, M

There is a growing awareness that awareness that environmentally assisted creep plays an important role in integranular stress corrosion cracking (IGSCC) of NiCrFe alloys in the primary coolant water environment of a pressurized water reactor (PWR). The expected creep mechanism is the thermally activated glide of dislocations. This mode of deformation is favored by the relatively low temperature of PWR operation combined with the large residual stresses that are most often identified as responsible for the SCC failure of plant components. Stress corrosion crack growth rate (CGR) equations that properly reflect the influence of this mechanism of crack tip deformationmore »« less

Stress-corrosion cracking and surface-pitting tests of NiCrFe alloy bolts (LWBR development program)

Technical Report Keller, K

Accelerated corrosion tests confirmed the adequate resistance to stress corrosion cracking (SCC) of the specific heats of NiCrFe X-750 and NiCrFe 600 used as bolts in the LWBR. SCC acceleration was achieved by running autoclave corrosion tests at 680/sup 0/F (well above the LWBR core operating temperatures of approximately 525/sup 0/F to 560/sup 0/F). Component stress levels were representative of maximum service stresses. No specimens from heats of either alloy suffered SCC.
Influence of analysis, heat treatment and structure on susceptibility to intergranular stress corrosion cracking of nickel--chromium--iron alloys (Alloy 800 and Alloy 600)

Book Carlen, J; Blom, U

From international nuclear industries fair; Basel, Switzerland (16 Oct 1972). Corrosion tests on a variant of Alloy 800 (Sanicro 30) in a modified Strauss solution have shown that the resistance to intergranular corrosion can be improved by a production sequence giving a small grain size and a high degree of stabilization. An investigation has also been performed in contaminated high- pressure water (100 ppM Cl/sup -//8 ppM O/sub 2/) on double U-bends of strip in Sanicro 30 and Alloy 600. This showed, for the inner U-bend in the crevice area, that the depth of intergranular attack depended on the typemore »« less
