To the Point: Heat Treating Aluminum Frames
For a little bit more elaboration on what Jeff was talking about with the crystal structure orientation allowing easy sliding or not, think of the following: a Rubik's cube where all the sides are lined up (normal looking). It is very easy to rotate the sides 90°, 180°, 360°. Now take the top level and rotate it 45°, take the bottom level and rotate that 45° (both relative to the middle layer). How easily will the sides turn now? It will break first! The crystal structure of metal deforms when there is a common slip plane available. No common slip plane = rupture rather than deformation, but also means much higher strength. Of course this is still over simplifying a whole ton of stuff involved, but still sheds a little light I hope...
