Abstract:

The mean specific heats of the refractory metals, niobium, tantalum, molybdenum, and tungsten, were calculated from theoretical considerations and also evaluated from experimental data above 1000 K. In the case of tungsten and molybdenum, the experimental data agreed extremely well with the calculated data. The mean specific heats of the four metals considered are very close together. They differ only by a maximum of 4 at 2000 K. Similarly, the mean specific heat of alloys made up of refractory metals is the same as that of the base metal. Thus, it is relatively simple to estimate accurately high temperature specific heat data for alloys made up of refractory metals. Author
