Metal doesn't "crystalize". As a Vice President of one materials lab and President of another materials firm I can say so with some authority. Now where there is Silicon in the alloy, local sites will exhibit crystals. The Japanese aluminm in the 30s had only small amounts of measured silicon.
Metal "crystalization" is an old wives tale told by people that aren't in the material sciences.
Sorry to bring this up but since it was mentioned twice I thought I should correct it.
