The figures are as follows: Fig. 1 Morphology of secondary γʹ precipitate of RR1000 (a) fine γʹ (b) coarse γʹ and statistics of γʹ size of (c) fine γʹ (d) coarse γʹ. Fig. 4 FCG rates (da/dN vs ΔK) found in tests on fine and coarse 𝛾′ microstructure variants with different testing frequencies at a temperature of 650 °C. Fig. 9 A trend of Sa and Sq of different loading frequencies at increasing ΔK. Note that Sa and Sq denote average height of selected area and root mean square roughness, respectively. Fig. 13 FCG rates of block tests of (a) fine 𝛾′ variant and (b) coarse 𝛾′ variant.
