The elastic properties and permanent set were investigated at room temperature for carbons made of graphitized filler and for carbons impregnated in the baked or graphitized state in dependence on the heat-treatment temperature. An apparatus for study of deformation at 1000 to 3000 deg C was built and calibrated and the first results for the variation of Young's modulus with ambient temperature were reported. Further studies of corrections to the heat conductivity from convection by gas across the pores were made and it is shown that such corrections are necessary even in the case of quite dense carbons. Transverse heat diffusivity was investigated at 700 to 2800 deg C by a transient state method, using a newly constructed apparatus; good fit with the previously found data in the low temperature range is obtained.
