Oliver Renk, Anton Hohenwarter and Reinhard Pippan Cyclic Deformation Behavior of a 316L Austenitic Stainless Steel Processed by High Pressure Torsion Advanced Engineering Materials 14
High pressure torsion of a biocompatible 316L stainless steel leads to a significant grain size reduction down to 50 nm. Fatigue experiments show that it is possible to generate cyclically stable microstructures at stress levels three times higher than for the coarse-grained material. Testing of different microstructures allows for a better understanding of the fatigue behavior of such nanocrystalline metals.
