Role of AlN/GaN Multilayer in Crack-Free GaN Layer Growth on 5”φ Si (111) Substrate

TiC interfacial layer is formed during titanium alloy to carbon steel diffusion bonding and prevents the formation of FeTi and Fe2Ti intermetallic compounds, which have detrimental effect on the properties of joints. The TiC layer is extremely thermodynamically stable in contact with austenite and is formed at the steel/titanium interface even in the case when carbon content is about 0.1wt.%. The evolution of an initially formed interfacial titanium carbide layer includes its growth and simultaneously changing the composition of austenite (towards lower carbon content) and titanium (towards higher carbon content). The kinetics parameters of the interfacial layer growth (carbon diffusion coefficient and the activation energy) reflect the grain boundary mechanism of carbon diffusion through the interfacial layer with submicron grains microstructure.

Critical Range

The role of waves on mixing is examined in a transverse shear flow in shallow waters for sub-critical, trans-critical, and super-critical flow over a range of convective Froude numbers. At low convective Froude numbers, the rollup of the vortex sheet to form an eddy defines the mixing. The mixing at higher convective Froude numbers, on the other hand, is affected by the shock waves and the radiation of the wave energy from an elongated vorticity element. Significant structural changes of the shear flow occur as the shock waves become discernible in the trans-critical and super-critical range of the convective Froude number. The shear layer growth is restrained while the momentum-thickness to vorticity-thickness ratio increases by a factor greater than 3. The fractional growth rate of the mixing layer in shallow waters and its dependence on the convective Froude number follows analogously the observed Mach-number dependence in gas dynamics.
