Abstract

The ordered AuCuII plates, formed during isothermal aging of equiatomic AuCu alloy, have a form and substructure in which the lattice invariant shear (LIS) produces a twinned product structure. Transmission electron microscopy measurements confirmed that the twinning is an appropriate variant required by the crystallographic theory and fractional twinning shear is consistent with the LIS required to ensure irrational habit plane is macroscopically invariant. Two variants of the superlattice structure of AuCu are within the individual twin variants and defining a domain substructure that develops after an initial formation of the twinned product. This may be interpreted to imply the existence of an intermediate product structure that is tetragonal.
