Lattice parameters have been measured in 18R and 6R martensite without
and with stabilization. It is shown that 6R is basically cubic, devia
tions occurring due to remaining traces of 18R. The orthorhombic disto
rtion in 18R depends on the long range order energy inherited from the
B2 phase, which generally is not perfect and can be modified by heat
treatments in the beta phase. Stabilization of 18R martensite can be q
uantitatively accounted for by the disordering of Cu-Zn pairs.
