You can hammer on gold until the sun grows cold, and you will not
increase it's density one iota. Hammering hot metal (usually iron or
steel) to increase its hardness is called tempering. It doesn't work by
increasing density. It works by fracturing the crystaline structure of
the metal, thereby establishing internal stresses. I suppose that
tempering could affect the hardness of gold, but it would never come
close to that of steel.
