摘要：
PROBLEM TO BE SOLVED: To produce an aluminum alloy material having a structure refined into the grain size of =220%, preferably, >=10000% is applied in the extruding stage to refine the average grain size in the microstructure to >=1 micron, by which the high strength and high toughness material can be produced. The extruding stage is executed at less than the recrystallization temp. of the alloy to be used, preferably, at less than the recovering temp.
