| Abstract Scope |
Creep degradation occurring near a material's yield stress can significantly limit its lifetime, even temperatures below conventual expectations (i.e., < 0.3 Tm). However, the investigation of low-temperature creep behavior is often hindered by long test durations and comparatively lower strain rates, with accelerated techniques often evaluating alternative mechanistic regimes. This work explores the underlying dislocation glide mechanisms influencing low-temperature creep of 316L stainless steel. Relevant microstructural factors inform combinations of indicator techniques used to identify significant creep deformation, which are implemented in conjunction with a high-throughput creep testing setup. The relative efficacies are evaluated for assessing the extent of material degradation and the material's state within its lifespan as well as for predictions of future performance within a stoichastically distributed material space. |
