Effect of Surface Nanocrystallization on Fatigue Behavior of Pure Titanium

Journal of Materials Engineering and Performance, 2015
The high-cycle fatigue behavior was investigated in pure titanium after surface nanocrystallization (SNC Ti). Compared with the coarse-grained titanium (CG Ti) samples, the SNC Ti samples exhibit an improved fatigue life. The SNC has a remarkable influence on the fatigue cracks initiation and growth of pure titanium.

Surface Nanocrystallization of Nb-Ti Stabilized 439M Ferritic Stainless Steel

Journal of Iron and Steel Research International, 2014
A new nanocrystallization process was designed, which included punching the surface coating to generate dislocation network or cells and recovery treatment to turn the dislocation cells into nano-sized grains. The effort was made to increase the service life of Nb-Ti stabilized 439M stainless steel surface with medium passive ability, particularly to ...
