STRENGTHEND Al,Zn ALLOYS BY LIQUID EXTRUSION
液态挤压下 Al,Zn 合金的强韧化

The liquid extrusion has been given on the basis of the theoretical research andthe experimental research of liquid forging.It makes liquid metal solidify under high pressureand then undergo plastical deformation,so the alloys structure is changed from the structure ofliquid forging into the structure of large deformation.The causes of the strengthened mecha-nism includes the crystallizing under pressure,the plastieal flow of extrusion and the flow of thequasi-solidified metal.So that mechanical properties of alloys have risen greatly.A great deal ofexperimental work has been performed,and the results have coincided with the one.
