Experimental investigation of the caloric properties of tungsten and graphite near their melting points

The authors present experimental data on the specific heat of tungsten in the temperature range 3000--3600 /sup 0/K and the heat of fusion, obtained over a wide range of specimen heating rate and ambient gas pressure. The specific heats of MPG-6 and pyrolytic graphites were investigated in the temperature range 3000--4200 /sup 0/K and at ambient gas pressure of 30--100 MN/m/sup 2/.
