Fig.3 Interface relationship between secondary phase and tungsten matrix and examples
(a) schematic of differences between metal and oxide^[70] (F represents force)
(b) HRTEM images of small particles within Y₂O₃ grains (b1, b2), W and Y₂O₃ interface (b3, b4), and small particles within W grains (b5, b6)^[87]
(c) HRTEM image of the TiC/W interface (c1), the fast Fourier transformation (FFT) patterns of areas marked by blue and red dash-line in Fig.3c1, respectively (c2, c3), the parallelism between (
