Abstract
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.
