To the Point: Heat Treating Aluminum Frames
This is not correct. The initial heat treatment is to dissolve the alloying elements in solid solution (solution anneal). The artificial aging causes very fine and evenly distributed precipitation of solutes inside each aluminum grains structure. There is absolutely no crystal structure transformation. The shear transformation you are describing occurs when hot steel is quenched and then followed by a lower temperature thermal treatment.
