an important method, which can transform the lamellar crystal structure of kaolin into disordered metakaolin structure by controlling the number of hydroxyl groups. Some original groups in the inner layer... temperature to 250 °C. There are two endothermic peaks at 40.7 and 230.3 °C ascribed to the removal of physical absorbed water and the removal of layer hydroxyl water, resulting in the mass loss of 0.49 wt......
process [11-14]. A great deal of research has been carried out and many new theories have been proposed regarding size effects. Based on the metal physics theory, grains in the surface layer of specimens... that the influence of grain size, geometric size and feature size should be considered simultaneously when analyzing the micro-sized material deformation behavior. Combining the surface layer theory......
of liquid metal was achieved by gradually activating the horizontal unit layer. The activation speed of the unit layer and the water-cooling boundary moved upward at a speed equal to the casting speed......
)). No transition layer is found between Al2O3 and the Mo matrix in sintered Mo sheet doped with Al2O3, similar to findings by ZHOU et al [22]. The appearance of such an interface may be attributed to the plastic... layer with dimensions of 3-8 nm exists between α-Al2O3 and the Mo matrix. The crystallographic orientations at the interface are and . (3) Microcracks appear in the Mo-Al2O3 alloys......

) because the defects such as Ni-P/SiC pores are filled by PTFE particles. 2) Compared with Ni-P/SiC modified layer, the corrosion resistance of Ni-P/SiC/PTFE modified 316L stainless steel has been... for corrosion durability showed that the corrosion current density of Ni-P/SiC/PTFE coating approached 0.19 μA/cm2 after working for 5 h. 3) The Ni-P/SiC/PTFE modified layer has a uniform and dense......
can not only make the polymer embed into the interlayer to form the embedded nano-material, but also make the sheet layer evenly disperse in the polymer to form the laminated nano-composite material... structure (mostly organic montmorillonite). In these two structures, the layer of montmorillonite dispersed in the asphalt will restrict the movement of the asphalt molecular chain to a certain extent, so......
of P in Cu-Cr-P alloys are designed according to the previous study [7]. Table 1 Chemical compositions of Cu-Cr-P alloys (wt.%) The oxide layer and defects on the surface of the ingot were removed. 20... removing the surface oxide layer, they were subjected to 95% deformation cold rolling by the two-roll mill, and then aged at 450 °C for 1 h. The electrical conductivity of the samples at room......
fabricated by SHB are shown in Fig. 7(a). It is shown that the most improvement of quasi-static compressive strength is obtained for Mg-5.0%B4C. The hardness of B4C microparticles and a thin layer... plastic deformations. This thermal energy generates a softened or molten layer that in turn enhances the bonding between the particles. This mechanism consequently increases the green density......
of single-layer twinning disconnections. The pile-up of twinning disconnections should be responsible for the wide steps at twin boundaries as observed in high-resolution transmission electron...-density presence of basal SFs inside deformation twins under HRTEM [33]. Besides, profuse I1 SFs (defined as in hcp systems by removing one basal layer followed by a slip of ) induced by basal......
