Shuang Gao, Yizhou Zhou, Zhi-Quan Liu, Tao Jin. Intergrowth of C phase within μ phase in a Re-containing Ni-base single crystal superalloy[J]. J. Mater. Sci. Technol., 2018, 34(5): 806-810.
Fig. 1. (a) BF image, (b, c) DF image and (d) SAED pattern obtained from circle region of μ/C intergrowth structure marked in (a). DF image of (b) and (c) were obtained with the diffraction spot of (1-12)μ and (-10-1)C, respectively. Schematic illustration of (e) shows the diffraction spot overlapping of μ phase and C phase. Insert white squares in (a-c) was enlarged and analyzed through element mapping below.
Fig. 2. BF image of (a) and element mapping of (b) Ni, (c) Co, (d) Cr, (e) Mo, (f) Ta, (g) W and (h) Re showing elements distribution in μ/C intergrowth structure.
Fig. 3. BF image of C phase in (a) blocky and (b) rod-like shape and SAED pattern of (c) showing a certain orientation relationship between μ phase and C phase. SAED patterns of (d-f) obtained along [10-1]C, [-131]C and [3-4-1]C.
