• Copper and zinc form solid
solution up to ~ 39% zinc at
456
oC, giving a wide rage of
properties.
• Sn, Al, Si, Mg, Ni, and Pb are
added elements, called ‘alloy
brasses’.
• Commercially used brasses can be
Microstructure of α brasses
• Microstructures of the singlephase
α brasses consist of α
solid solution.
• Annealing twins observed in
the α grains increases with the
Zn contents.
• Dislocation structure also
changes from cellular to welldefined
planar array structure
with increasing Zn. (due to
lowered stacking fault energy).
