• Internal friction and the period of vibration of an orderable alloy Au,Cu aremeasured as functions of temperature between about 310 K and 870 K both in heatingand in cooling runs with a fully automatic torsion pendulum. Three internal frictionpeaks P., P, and P. are observed at about 490 K, 625 K and 760 K, respectively. Thepeak P. which appears only in a quenched specimen and anneals out around its peaktemperature is considered to be related to a rapid order-disorder transition enhancedby excess vacancies. The peaks P, and P. are identified with the Zener peak and thegrain boundary peak, respectively. The effects of heat treatments and deformation onthese peaks are investigated, and the results are compared with those of a similar alloyC u,Au.
