In this paper, time-temperature-precipitation diagrams were determined between 400° and 900°C for up to 3000 hr as a function of carbon content, solution treatment temperature, and cold work.Abstract:
Although Type 316 austenitic stainless steel is widely used in steam generating plants and nuclear reactors the knowledge about aging reactions, nature of precipitates, and precipitation kinetics during high temperature exposure is limited. Time-temperature-precipitation (TTP) diagrams were determined between 400° and 900°C for up to 3000 hr as a function of carbon content, solution treatment temperature, and cold work. The nucleation and growth phenomena, morphology, and composition of the various carbide (M23C6, M6C) and intermetallic phases (σ, χ, η were determined. The complex sequence of phase instabilities can be explained on the basis of the carbon content, effect of molybdenum and chromium on the carbon solubility, thermodynamic stability of the phases, and the kinetics of the various precipitation reactions.read more

Precipitation formation on ∑5 and ∑7 grain boundaries in 316L stainless steel and their roles on intergranular corrosion

TL;DR: In this article, the authors applied GB energy anisotropy to explain the faceting phenomenon and the formation of two kinds of precipitates, i.e., C14 Laves phase and M23C6 carbide, holding responsible for two distinct morphologies of corrosion, are believed to be both linked to intensive faceting and the anisotropic segregation of ∑7 grain boundaries.

The effects of grain boundary precipitates on cryogenic properties of aged 316-type stainless steels
TL;DR: In this paper, a study of low carbon stainless steels demonstrates that aging at sensitization temperatures results in the formation of grain boundary intermetallic compounds or nitrides instead of carbides.

Comparison of load relaxation data of type 316 austenitic stainless steel with Hart's deformation model
TL;DR: Load relaxation experiments have been performed on Type 316 stainless steel at temperatures up to 650°C as mentioned in this paper, and the resulting stress-plastic strain rate relationships below 500°C show the behavior of a plastic equation of state.
