For the wider alloy of liquid quadrant, solid-liquid is a kind of melt state that can be controlled, thus is processed to it as can
Energy.Under normal circumstances, there is dendrites in alloy, these dendrites are on the one hand mutually difficult to slide, affect the change of material
On the other hand shape ability is unfavorable for dislocation motion, influences the mechanical property of alloy.With traditional liquid and formed solid method
It compares, semi-solid forming technology has the characteristics that its peculiar and advantage, exists admittedly in melt when semi-solid forming technology has casting
The features such as state primary phase, alloy viscosity is high, resistance of deformation is small compared with solid-state, slurry can be separated by solid-liquid separation.Compared to traditional liquid
Forming method, semi-solid forming technology are with the obvious advantage, and formation of parts contraction is small, and internal flaw is few, and stock utilization is high, molding is all
Phase is short, the advantages that can be used for preparing complex structural member.Semi-solid forming technology is divided into as two works of thixotropic forming and rheological molding
Skill route.Compared with thixotropic forming, rheological molding has many advantages, such as that flow is short, low energy consumption, at low cost.Semi-solid rheological is cast into
Type method is a kind of semi-solid rheological molding technology developed recently, that is, uses semi solid slurry of the compression casting technology to acquisition
Processing is formed, the advantages of which has both semi-solid rheological molding and compression casting, is a kind of potential semisolid stream
Become forming technique.
At present in business applied to the magnesium alloy of semi-solid processing be mainly it is traditional be free of rare earth cast alloy, especially
Mg-Al systems alloy, such as AZ91, AM50 and AM60.But from the point of view of semi-solid-state shaping, Mg-Al systems are free of rare earth alloy simultaneously
It is not ideal semi-solid alloy, heat treatment reinforcement effect unobvious, it is difficult to play the heat treatable advantage of semi-solid products.
Therefore, novel semi-solid-state shaping alloy should be developed and give full play to semi-solid-state shaping to meet the needs of various different structure parts
Whole advantages.First technology, " the antiflaming magnesium alloy semi-solid rheological extrusion casint forming side of publication number CN 104001895A
