Abstract

Microhardness of stoichiometric CuAu was measured during isochronal heating starting from the disordered and the ordered state as well as for isochronal cooling from the disordered state. It is shown that a continuous increase of long-range order connected with similar hardness behaviour was observed in all cases of thermal treatment and pre-treatment. In correspondence with earlier resistometric experiments during isochronal temperature variation no hysteresis between heating and cooling was observed.
