Fig.10. Fatigue striation characteristics at different fracture locations (distance from crack initiation site) of 316LN stainless steel hollow specimens at different strain rates of 0.4 × 10-2 s-1 (a, d, g), 0.04 × 10-2 s-1 (b, e, h), and 0.004 × 10-2 s-1 (c, f, i) (The line in the figure dencotes the fatigue crack propagation direction, and the number is the average fatigue striation spacing in the line length area, unit: μm/cyc)
