TLDR
In this article, a nanocrystalline 316L austenitic stainless steel sample (mean grain size similar to 40 nm) was prepared by means of surface mechanical attrition treatment, which exhibited an extremely high yield strength up to 1450 MPa, which still follows the Hall-Petch relation extrapolated from the coarse-grained material.About:

Deformation mechanisms in meta-stable and nitrogen-stabilized austenitic stainless steel during severe surface deformation
TL;DR: AISI 304L stainless steel in austenitized and in solution nitrided condition was severely mechanically deformed by surface roller burnishing, leading to a depth-gradient in the austenite stability as mentioned in this paper.

Severe shot peening of AISI 321 with 1 000 % and 1 300 % coverages: A comparative study on the surface nanocrystallization, phase transformation, sub-surface microcracks, and microhardness
TL;DR: In this article, AISI 321 austenitic stainless steel samples were surface treated using severe shot peening (SSP) with 1 000 % and 1 300 % coverages, and microstructural features including the grain size, phase transformation, and formation of sub-surface microcracks were investigated at the rough top surface and about 40 μm depth.
