RI 3419 Progress Reports - Metallurgical Division ? 25. Annual Report Of The Metallurgical Division, Fiscal Year 1937-38 ? Metallurgical Fundamentals Section

[During the past year the Metallurgical Fundamentals Section gave about an equal amount of time to the experimental determination of fundamental thermodynamic constants and to the demonstration of the application of such data to more directly practical metallurgical problems. The first division of the work - the actual experimental measurements of typical thermodynamic constants - was carried out an two problems, termed ?continuing? programs, namely, (1) measurements of Specific Heats at Low Temperatures and (2) Measurements of Heats of Formation and Free Energies. Specific substances chosen for investigation are classified as (n) those that have been the subject of requests for information from the industry and that, upon examination, seem of sufficient practical importance to justify study, and (b) compounds that are difficult to treat metallurgically, or whose specific thermodynamic properties have not yet been determined satisfactorily and for which accurate data might suggest improved or new methods of Metallurgical treatment, or (c) materials recognized as belonging to a social class with exceptional thermodynamic properties and, hence, of scientific as well as technical importance.]
