Detailed analysis of the interface structure between W matrix and second phase particles in WZC.

(a) HRTEM image of W matrix and ZrC phase (intragranular) as viewed along [001]. (b) The SAEDP revealing the particle with a face centered cubic structure. c, Fast Fourier transform (FFT) pattern of selected red square area A on ZrC. (d) FFT pattern of selected red square area B at interface area between W and ZrC. It is clear that the particle-matrix phase boundaries have coherent structure like showing in high magnification (e). (f) TEM image showing a deadbolt shaped ZrC particle (intergranular) tightly locking two tungsten grains (G1 represents the right one and G2 represents the left one). (g) Semi-coherent structure appears between the ZrC dispersoid and G2. (h) Some relative large particles locating at GBs of tungsten contain W, Zr, C and O elements through i, EDX analysis.
