of Alloys and Compounds, 2009, 468(1): 164-169. [16] WANG Lu-yuan, HUANG Jian, PENG Yong, WU Yi-xiong. Precipitates evolution in the heat affected zone of Mg-Gd-Y-Zr alloy in T6 condition during laser......
via the WO2(OH)2 vapor phase and vapor-solid reaction [3,24]. Figure 2(c) shows the morphology of the W powders that are hydrogen-reduced from WO2.72, and the granulated shape of the W powders.... The sudden rupture of hard agglomerates causes the sudden variation of pressure, which produces the sharp jump at the end of Curve 1, thereby forming a broadening zone at the end of Curve 1......
diversity and detection of microorganisms. This technique combined with the method called interphase fluorescence in situ hybridization (FISH) coupled with polymerise chain reaction (PCR..., which hindered the dissolution action at high temperature at 50% of copper recovery. On the other hand, this means that the diffusion control is less accelerated despite an increase in temperature......
not be accommodated into the bulk volume of the material due to this barrier effect, and the plastic zone is confined to the area near the indentation, which results in the presence of pile-up. 3.2......
ratio also affects the transition zone between fiber and matrix and interface bond decreases at higher W/B ratios. In particular, high affinity of PVA fibers with cementitious matrix may result in fiber......
of such a structure can be discussed as follows. New intercrystalline boundaries formed during rolling served as the sites of preferential nucleation of precipitates. And increase in the diffusion rate along the cell... in the IGC resistance of cold-rolled steel was explained by the increased dislocation density, which resulted in the increased diffusion rate along dislocation pipes and, accordingly, intensified......
of the driver in a dangerous situation [29], such as the steering wheel or brake pedal operation, will exceed the operating range of normal driving, where the driver’s reaction is instinctive and subjects to human physical and psychological restriction of reaction ability. During the driving process [30], most of the dangerous situations occur suddenly, and traffic accidents are very likely to occur later......
field zone is created in a very short interval of time after the incident shock wave is reflected back. The equations describing the change in pressure and temperature with respect to the speed......
[22], and hence, it can be formed more easily in the micro-arc discharge zone through rapid cooling of molten alumina when it contacts the surrounding cold electrolyte. However, the thermal stability... resistance of the coating. The higher the voltage is, the stronger the electric field is. Consequently, raising the voltage can augment the driving force of PEO and improve its reaction rate......
of inert metals clearly indicates that appearing of hydrogen evolution as a parallel reaction plays a crucial role in the formation of Ni-Co powders by electrolysis processes. Investigations... that electrodeposition processes of Ni, Co or Ni-Co catalyzed the reaction of hydrogen evolution [31]. Formation of hydrogen bubbles at high current density represented the rate limiting step......
