Fcg path
WebWe are trying to figure out what the FCG mechanism is and build up some relationship between the mechanism and FCG path. Best wishes! Looking forward your solution! Cite. 1 Recommendation. WebJan 14, 2024 · This research focused on the impact of temperature and driving force ΔK on the fatigue crack growth (FCG) mechanism of C-276 Ni-based weld metal in a 9% Ni steel joint. On one hand, the FCG resistance increased due to higher yield strength at 77 K than at room temperature (RT), and the decrease of FCG rate can be well explained by …
