KINETICS OF FATIGUE FRACTURE OF TITANIUM IN THE SUBMICROCRYSTALLINE STATE [№ 9 ' 2012] It is shown that ECAP-conform, forming sub microcrystalline structure, increases the fatigue limit of titanium Grade 4, by increasing the time to fatigue crack nucleation and the slower speed of its spread, as compared to baseline. However, the exponent n in the Paris's equation more than about 2 times. This demonstrates the sensitivity of the material to stresses during operation. |
