When heating up an piston and cooling it down the copper molecules do change the structure of the piston alloy giving also some grow when cooled down.
With every time the alloy is heated up more than before this proces is restarted again. Finally it can give more strength in the piston but so far no noticable differences are realy found when doing it al in one long break in proces.
