Background technique
Aluminium alloy semi-solid casting has achieved in the fields such as high-pressure casting, extrusion casint, liquid forging more
Using being made that the good product of inherent quality, also reached high production efficiency.In the production practices of semisolid, high die casting
When making the thin-wall part of aluminium alloy, when the higher liquid aluminium alloy of discovery pressure injection temperature is filled, often there is the scarce side of underpriming
The phenomenon that few meat phenomenon when can use semi-solid aluminium alloy, compares pure liquid, misrun occurs less, this turns out semi solid slurry
Expect that filling thin-walled ability is also higher than the molten aluminum of pure liquid.It is with almost spherical that it, which has its source in when semi solid slurry crystal grain is grown up,
Appearance grow up, when there being a small amount of liquid, its liquid has acted as lubricant when filling thin-walled, make spherical crystal grain to
Resistance is smaller when filling at thin-walled, it is easier to it is full of, and pure liquid metal acutely quickly forms at filling thin-walled place due to cooling down
Netted dendrite blocks the flowing of liquid metal, and cellular dendrite is to be difficult to roll or put down in the two phase flow that liquid coexists admittedly
It moves, therefore the ability of the filling thin-walled part of the pure liquid aluminium alloy of high temperature can not show a candle to semi solid slurry.
