“…Nonetheless using these interaction parameters, a recent MC calculation 70 yields a qualitative correct picture of the phase diagram including the two-phase field A2-B2. One essential ingredient for this success was probably that the magnetic coupling was treated by the Heisenberg model allowing for a continuous degree of freedom for the Fe-spins.…”

An introduction is given into the Monte Carlo technique of phase diagram calculations. Beside the standard approaches used to determine first and second order phase transitions, a most promising development is discussed, namely the analysis of the probability distributions by histograms. Applications to real alloys are considered, such as the decomposition in Cu-Co and Cu-Ni, the short-range order and critical scattering in Cu-Au type alloys, the phenomenon of surface induced order in Cu-Au models having a free (100) surface, and the interplay of magnetism and chemical ordering in Fe-AI.

Thispaper summarizes the chief trends in the development and applications of potentiometric methods of analysis since the last review in this series (152), covering the period from January 1962 to December 1963.Bates and Guggenheim (17) have reviewed the degree of standardization of pH terminology and standard buffers in Great Britain, United States, and Japan. Van Rysselberghe (235) has examined possible definitions of pH at low and at high ionic strengths and compared these with some aspects of the report on the standardization of pH by Bates and Guggenheim (17). Many practical aspects of pH measurement have been described by Mattock (14-2).
