ORDERING AND DISORDERING PROCESSES IN CU3AU II
Abstract
Data are reported which describe both the equilibrium and kinetic change of length with order in a single crystal of Cu3Au. Equilibrium values of the order dependent change in length per unit length with temperature are given for the region 218 to 500 C by combining these data with the lattice parameter values of Feder, Mooney and Nowick (Acta Met. 6:266, 1958). The isothermal variation of length with time following a sudden change in temperature is studied for changes below the critical temperature when the specimen is initially in various states of long-range order as well as for quenches through the critical temperature where there is no initial longrange order. The experimental data are compared with the description of the phenomena offered by various equilibrium and kinetic theories. (Author)
