Nanocrystalline material with gigacycle fatigue life.
Copyright policy )Nanocrystalline material with gigacycle fatigue life.
A processing technology has been developed that can be applied to many different fine wire medical alloys to improve their fatigue properties. This technology has been used to process a low inclusion alloy, 35 cobalt-35 nitinol-20 chromium-10 Molybdenum (ASTM F562 chemistry), hereinafter referred to as System A. After processing, this ultra fine microstructure exhibited relatively high yield strength, good axial ductility and a fatigue limit of 1 GPa at a fatigue lifetime that exceeded 100 million cycles, as reported here.
