Classical thermodynamic equations based on the regular solution approximation yield enthalpic changes for eutectic transformation that agree roughly with values measured for several binary and ternary alloy systems by differential scanning calorimetr

Continuous measurement of X-ray transmission through a sample confined in a rigid holder permits thermal expansion coefficients of solids, density change during melting, and thermal expansion coefficients of liquids to be determined by a single metho

Diffusion coefficients and marker movements have been determined in β brass using welded couples. Three different concentration ranges were employed at 750°C, while a fourth concentration range was measured at 500°, 600°, 700°, and 800°C. Marke

The pressures and mean molecular weights of the vapors over solid antimony (420–550°C) and solid zinc (250–335°C) have been determined by simultaneous measurements by the torsion‐momentum and Knudsen weight loss methods. The torsion measureme

Self-diffusion measurements have been made in the semi-conducting interrnetallic compounds InSb and GaSb. The material was single crystal or slightly polycrystalline. A tracer technique was used, in which layer's were removed from the crystal progres

1—Diffusion coefficients in the Cu-Pd system have been determined as a function of temperature and concentration. The concentration dependence is slight in both extremes of concentration and strong at intermediate concentrations. The diffusion coef
