) and Tecnai G2 F20 S-TWIN transmission electron microscope (TEM). The plane-view TEM foil of melted layer was obtained firstly by polishing the sample mechanically on the untreated side until it was about 50... keV, the ion beam current of 0-8 μA. The microhardness of the cross-sectional plane of the melted layers and the substrate were measured by a HVS-1000A Vickers tester with a testing load of 5 g......
of Raman spectrum of free carbon are induced by disorder carbon and in-plane bond stretching of sp2 carbon, respectively. In addition, two peaks of β-SiC are obvious in Raman spectrum of CVI-SiC [9,11,12... composites is very plane and no pull out fibers can be seen in Fig. 7(a). For the composites oxidized for 2 h shown in Fig. 7(b), obvious pull out fibers dominate the fracture surface indicating the weak......
in the gliding plane, dislocations can not glide freely. In different subgrains, the dislocation density is different. Figure 4(c) shows the high magnified image of the no-dislocation area by another......

deformation was carried out on the plane taken from the mid-section of the deformed samples. The specimens for observing microstructure were mechanically polished using SiC waterproof papers (grade......
from a gate located at the center of the mold bottom plane. A reversed T-shape obstacle is positioned inside the mold. In the present work, two flow rates with fluid injection velocity v=0.45 m/s and v......
situations. 1) Assuming that the reaction does not change the global drop composition significantly, hence the σLV is constant with time at the triple line. 2) If the triple line remains on the plane......
