Noticeable yield point differences exist upon comparison of the 0% pre-strained sample (initial quasistatic tensile testing to failure) and the yielding behavior of the reloaded samples, and this difference is attributed to room temperature strain aging
following pre-straining as noted in Figure 2(a).
However, because cold forging causes a temperature increase due to plastic deformation, it is also necessary to consider dynamic strain aging 2,3).
As a result of the temperature increase caused by plastic deformation during cold forging, dynamic strain aging due to solid solution N is considered to increase work hardening 6).
During those tests for carbon steel material under hot temperatures, a strain aging
effect can be developed.
Reduction of the plastic properties of metal pipes is due to strain aging
and may cause a discrepancy of mechanical properties regulatory performance, and in some cases, the cause of brittle fracture of pipelines.
Static strain aging
phenomena in cold-rolled dual-phase steels.
A phenomenological model of strain aging
When the slip step is large and strain rate is high as in the case of dynamic strain aging
, we have observed a spike of AE activity.
The hot air stress strain aging
results for 504 hours at 150[degrees]C are presented in figure 6.
During heating, the carbon atoms in the steel collect around the dislocations, a process called strain aging
, Murr says.
