A technique of grain refinement and semisolid alloy preparation was introduced

and its research and applications in recent years have been summarized.The vibrating sloping plate process can significantly refine grains size in alloys

and the grain size in pure aluminum can be refined to one grade easily by the vibrating slope plate process.In addition

the primary Si and eutectic Si in hypereutectic Al-Si alloy can be well refined by the process.The semisolid billets such as A356

Al-6Si-2Mg

A2017

AZ91

AZ31 and hypereutectic Al-Si alloy with fine spherical structure or equiaxed grain have been prepared by the vibrating sloping plate process

and the thixoforming of the semisolid billets has been conducted.The tubes

profiles and wires of the alloys such as 6201

A2017

AZ31 and AZ61 alloy have been manufactured by continuous semisolid extrusion

and the strips of the alloys such as A356

A2017

AZ91

AZ31

AZ61

and Mg-Sn alloy have been produced by semisolid rheo-rolling.Due to the vibrating sloping plate process exhibiting the advantages of low cost and high efficiency

it has a good application prospect in the fields of rheo-diecasting

rheo-extrusion

rheo-rolling

microstructure refinement of metal

and so on.
