Why might copper have and air bubble?
Small, closely spaced water vapor bubbles are formed along grain boundaries in coarse grained copper by annealing first in air at 800°C and then in hydrogen at 600°C. Almost all of the cavities are formed at grain boundaries, primarily because oxygen strongly segregates to grain boundaries in copper.
