“…3. The results of resistometric measurements by Borelius and Jonsson [6] at 28 at 96 Ni, calorimetric measurements by Nystrom [7] at 26 96, and resistometric measurements by Underwood [27] at 33, 50, 64 and 81 0; are in good agreement on the same line.…”

Different spinodal hypotheses are discussed. An analysis of experimental results shows that the passage of the classical spinodal has a marked influence on the rate of the initial decomposition of supercooled homogeneous alloys both when the decomposition is continuous, as in the AuPt-alloys, and when it takes place at the front of a discontinuous precipitation, as in AuNi-alloys. The preference of the discontinuous to the continuous precipitation in AuNi-alloys at high temperatures is made understandable by a discussion of the activation energies of different types of diffusion.

“…(2) The Q-values of diffusion at the front of the cellular precipitation are obtained from Arrhenius-plots of log t against 1/T, where t is a half-value time or some other part-value time, determined from the measurements of Borelius and Jonsson [6], Nystrom [7] and Underwood [27]. They are marked by circles in Fig.…”
