文摘This paper investigates the production of pure aluminum by using traditional metallurgy and nanotechnology. To make a pure aluminum stronger, extremely cold and mechanical manipulation process was employed and followed by carefully heat treatment cycle. The practical produetion and testing showed that the higher the stored dislocation＇s density after rolling was, the finer the recrystallized grains during heating were. In aluminum, these new grains were only a couple of nanometers in size, several hundred times smaller than the original crystals, making the aluminum much stronger than its original form.
