Put risers at heavy sections so solidification occurs first in the thin sections, then the medium sections, then the heavy sections, and then the risers.
As a new type of green solidification control technology, the ECP, which conducted in alloys through electrodes directly contacting the melt, can improve the heterogeneous nucleation rate of liquid metal or semi-liquid metal, promote the solute redistribution, and refine the solidification microstructure [6-9].
In order to induce directional solidification chills, risers, insulating sleeves, control of pouring rate, and pouring temperature can be utilized.
Duration of the main solidification and the ice cooling stages were found to be dependent on the drop size.
Five invited lectures explore such topics as the in situ observation method for the quantitative evaluation of solidification phenomena and solidification cracks during welding, investigating the effect on microstructure of changing fluid flow characteristics in high pressure die casting, and the effect of sample mount on active screen plasma duplex processing.
"Solidification happens all around us, either naturally, as during the crystallization of familiar snow-flakes in the atmosphere, or in technological processes used to fabricate a host of materials, from the large silicon crystals used for solar panels to the making of almost any man-made object or structure that needs to withstand large forces, like a turbine blade," Northeastern University Prof.
Researching the transition process of liquid to solid and the microstructure evolution law during rapid solidification are research hotspots in condensed matter physics and material science [1].
A major impediment to the process is thermal interaction with a container wall, so electromagnetic and electrostatic levitation techniques have been developed for containerless undercooling and solidification of molten metals and alloys.
