Abstract
Microstructures in a copper-aluminium-nickel shape-memory alloy are constructed using a geometrically nonlinear theory of martensitic transformations. All of the twins and habit planes are found, and a detailed comparison with experimental data is presented. Further, it is shown that twinned wedge microstructures with both type I and type II twins are possible in this alloy because its lattice parameters satisfy a special relation.
