316L specimens by dipping the specimens in molten Al–Si melts for 2 min in reduced atmosphere containing hydrogen gas with the help of nozzle [59]. Afterwards, half of the specimens were diffusion.... High electron affinity of Si towards Fe is responsible for the diffusion limiting behaviour of Si as reported by EGGELER et al [70]. Step by step moving to equilibrium composition close to coating......

different recognition methods to perform drum cutting pattern recognition tests and the results certified that the least squares support vector machine coupled with improved fly optimization algorithm... of cutting torque itself, the total drum torque presented exponential growth. Figure 8 Photo of 650 mm width test drum The drum torque value was 1840.24 N·m, which was very close to the maximum torque......
of excess air ratios, inlet temperature and cooling. For simplifying the calculation model, hydrogen/air one step reaction is used. Three-dimensional steady implicit solver based on pressure is used.

. As the running speed exceeds 250 km/h, the running speed of HSTs has less effect on the snow accumulation on the bogie. The snow accumulation on the bogie surface at the running speed of 250 km/h is close... system for wheels, multi nozzle snow making system, and single stage screw refrigeration unit. The flow field in a real bogie cavity (1:1) at the lower temperature with different yaw angles can......
as a shielding gas, supplied to the treatment zone under a pressure of 0.6 MPa using a cylindrical nozzle. 3 Results and discussion 3.1 Microstructural evolution during mechanical alloying The formation......
of the velocity tensor. According to Figures 4-6 and the above 2 animations, the flow under the train bottom is similar to the jet flow in the Laval nozzle, changes violently due to the narrow space, and produces the complicated flow structures here. On the whole, this flow can be divided into two parts: up and down. The up part is close to the train bottom, and is a low-speed, strong-vorticity......
