Abstract
The precipitation kinetics of an advanced austenitic steel, modified with stabilizing additions of titanium, niobium and vanadium, has been studied in both the solution-annealed and the solution-annealed plus cold-worked conditions, for times up to 3000 h at 800°C. Matrix phosphide precipitates and a very few MC precipitates evolved in the solution-annealed material. In contrast, stable MC matrix precipitate distributions were observed after only one hour at 800°C and persisted for 3000 h in the samples which were solution annealed and cold worked. Observations using transmission electron microscopy provide an explanation for the significant improvements in creep rupture strength observed in the advanced alloy compared with 316 stainless steel.
