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:

Investigation of microstructural evolution in a selective laser melted Ti6Al4V alloy induced by an ultrasonic surface rolling process
TL;DR: In this paper, surface modification treatment was carried out on a selective laser melted Ti6Al4V alloy using an ultrasonic surface rolling process (USRP) and the results showed that a deformed layer with a gradient microstructure was produced near the surface.

Grain boundary impurity and porosity effects on the yield strength of nanocrystalline materials
TL;DR: In this article, the effect of impurities on the equilibrium and nonequilibrium boundaries of nanocrystalline materials is analyzed and the strength of nanosize grains is shown to decrease with decreasing grain size in the range of nano grain sizes.

An investigation of surface nanocrystallization mechanism in Fe induced by surface mechanical attrition treatment
TL;DR: A grain refinement mechanism induced by plastic deformation during the SMA treatment in Fe was proposed in this article, which involves formation of dense dislocation walls (DDWs) and dislocation tangles (DTs) in original grains and in the refined cells under further straining.
