Answer:

No new substances formed, but some some chemical bonds broken......hmmmm. This is a physical change.

Explanation:

Chemical change is characterized by the formation of new substances and the making and breaking of strong chemical bonds. Cutting a melting in half, or even melting or boiling the metal do not satisfy these criteria.
