Most polycrystalline resources is often produced into huge single crystals immediately after extended heat remedy. Previously blacksmiths would warmth a piece of steel to really make it malleable: warmth makes a couple of grains grow big by incorporating lesser ones. The smiths would bend the softened steel into condition read more after which pound it awhile; the pounding would make it polycrystalline once more, increasing its energy.
