Antiphase domain boundary (APB) tubes have been observed in a slightly deformed Fe–30.5 at. % Al alloy in dark field electron microscope images taken in superlattice reflexions. The image contrast theory has been developed and accounts satisfactorily for the nature of the APB tube contrast observed. The contrast theory is used to estimate the heights of the tubes. The widths of the tubes range from 20 to 50 ņ, and the measured heights are in the range of one to six times the elementary height. Evidence is presented that tubes are generated by the Vidoz & Brown (1962) mechanism and by a mechanism of cross-slip and annihilation of screw superdislocations. The possible effects of tubes on flow stress are discussed.

Alloy Particles

Atomic structure of nanoscale particles of a Cu-Au alloy with a nominal composition Cu3Au and the phase transformation therein are studied by means of high-resolution electron microscopy and electron diffraction. The particles 8.8 nm in diameter on average prepared by simultaneous vacuum deposition of the constituent elements exhibit as a whole an fcc structure of an alloy with a composition of 26.4 at.% Au. The alloy particles are ordered into the L12-type superlattice structure when heat-treated at 563 K for 1 h. The superlattice reflections disappear upon heating up to 773 K. In a particle about 10 nm in size an antiphase domain boundary is observed. It thus appears that the nanoscale particles of the alloy undergo the order-disorder transition, as in the bulk. However, the critical temperature Tc for the order-disorder transition of the nanoscale particles is found to be by about 90 K lower than that of the bulk. The minimum size of the alloy particles in which lattice fringes whose spacing corresponds to the interplanar spacing of the {100}-type superlattice planes are observed is about 4 nm. These facts suggest that a certain critical size and size effects are present for atomic ordering in the Cu-Au alloy particles.
