The study looked at how Type 304 stainless steel behaves under repeated stress at different temperatures. They found that the steel's fatigue strength changes with aging, initially getting stronger but then weakening over time. The formation of carbide precipitates during aging affects how long the steel lasts under stress. The researchers showed that high-cycle fatigue data can be linked to low-cycle data by using stress-strain curves. The speed of stress cycling and the steel's initial history don't make a big difference in how it performs under stress.
