Non-Equilibrium Phase Crystallization of Al–Si Alloy Close to Eutectic Composition by Mechanical Vibration
نویسندگان
چکیده
The amount of the primary phase crystallized in a eutectic alloy at set cooling rate is determined by composition. Only small can be near-eutectic composition alloy. Here we show an interesting phenomenon which microstructure changed application mechanical vibration to Al–Si during from molten metal semi-solid state. α-Al obtained with more than equilibrium solidification. non-equilibrium phases, solidification, increases velocity amplitude vibration. phases had uniform shape that consisted fine spherical particles. These crystals same as solidified without Primary Si particles could also observed

Microrheology close to an equilibrium phase transition.
We investigate the microstructural and microrheological response to a tracer particle of a two-dimensional colloidal suspension under thermodynamic conditions close to a liquid-gas phase boundary. On the liquid side of the binodal, increasing the velocity of the (repulsive) tracer leads to the development of a pronounced cavitation bubble, within which the concentration of colloidal particles i...
متن کاملNon-isothermal Primary Crystallization Kinetics of the Amorphous Fe85.3B11P3Cu0.7 Alloy
In the present research, the primary crystallization kinetics of the amorphous Fe85.3B11P3Cu0.7 alloy was analyzed using non-isothermal DSC measurements. The average and local activation energies, Ea, were determined by different isokinetic and isoconversional methods. The results obtained for activation energy in this research, show that due to the complexity of the primary crystallization pro...

متن کاملPerformance improvement of vertical ultraviolet-LEDs with AlSi alloy substrates.
A composite AlSi alloy substrate was fabricated to eliminate thermal expansion coefficient mismatch in high-power vertical light-emitting diodes (VLEDs). At 2000-mA injection current, the light output power performance of LED/sapphire, VLED/Si, and VLED/AlSi are 1458, 2465, and 2499 mW and the wall-plug efficiencies are 13.66%, 26.39%, and 28.02%, respectively. The enhanced performance is attri...
