Cu 60, Zn 40 (wt%), air cooled - Widmanstätten microstructure
This sample has been air cooled. The fast cooling rate changes the morphology to a 'basket weave' appearance known as a Widmanstätten microstructure. The α phase precipitates out of the single β phase during cooling to give α plates in a β matrix. The plates form in order to minimise strain energy.
