· The diagram shows the dependence
of the UTS
and percent
elongation of various brass alloys on their composition.
· Cartridge brass has the maximum ductility
of the group but a UTS only 65% of that for Muntz metal.
· At the Muntz metal composition, the ductility
has been reduced to 15% of that for cartridge brass, but with a significant
increase in the UTS.
· The ductility
of Muntz metal can be increased by heating it into the single β-phase at about 850 C and hot
working the
material. Cooling to room temperature will restore the two phase structure
and associated properties.
