PURE-ALUMINUM STRUCTURAL MATERIAL WITH HIGH SPECIFIC STRENGTH SOLIDIFIED AND MOLDED BY GIANT-STRAIN PROCESSING METHOD

摘要

Disclosed is a structural material using novel, high-purity aluminum, which is produced by using fine aluminum powder as the material, as well as a method for manufacturing such structural material. A processed aluminum material having the properties of an aluminum structural material constituted by aluminum, aluminum carbide and unavoidable impurities except aluminum and aluminum carbide is characterized in that a material obtained by uniformly dispersing stearic acid in fine aluminum powder is filled in an L-shaped bent die, and pressures are applied to the material from one direction and the other direction of the die wherein the pressure applied to the material from the one direction of the die is greater than the pressure applied to the material from the other direction of the die, to cause the material to pass through a hole of the L-shaped bent die so that the material is given and accumulates giant strain, and this process is performed continuously.
