- W2286172014 abstract "A battery of three isothermal jacket microcalorimeters is specially conceived to study the evolution of small quantities of heat occurring over long periods of time at low temperature. At lOO deg C these calorimeters are capable of a sensitivity of 0.002 calories per hour and about twice this amount at 200 deg C. The calorimeters have been used for the study of the poorly known yet important order-disorder transformation of Au/sub 3/Cu. With the help of x-ray diffraction it has been shown that ordering of a previously disordered samphe proceeds in three stages. The first stage corresponds to the formation of short- range order, the second stage to the growth of long-range order donaains simultaneously with an over-all increase of the degree of order, and the third stage to a further growth of the domains aIone. The critical temperature has been determined as 209 to 212 deg C. It is believed that the reaction occurs in conditions such that equilibrium is not reached. As a result the usual classification of reaction into first, second, etc.. order does not apply. Thus, while the transformation is not marked at the critical temperature by a latent heat which can be experimentally detected itmore » would be meaningless to classify it as a higher order transiormation. The total enthalpy change between a completely ordered and a completely disordered sample is estimated to be 375 calories per mole from a maximum found that quenched-in defects presumably vacancies can play a very important role in ordering transformations. At lOO deg C, in a quenched sample. the rates of ordering can be more than a thousand times greater than would be calculated on the basis of the rates observed at 190 deg C. The quenched-in vacancies do not only contribute to the speed of the transformation, they also help in bringing the alloy closer to true equilibrium conditions than would be otherwise possible.
