Available in PDF, EPUB and Kindle. Book excerpt: Elastic properties and permanent set were investigated at room temperature for carbons made of graphitized filler (soft and hard) and for carbons impregnated in the baked or graphitized state in dependence on the heat-treatment temperature. An apparatus for study of deformation at high temperatures (1000 - 3000 C) was built and calibrated. Results for the variation of Young's modulus with ambient temperature were reported. Another improved apparatus for studies of heat conductivity at high temperatures was finished and also put into operation. Studies of corrections to the heat conductivity due to 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 in the range 700 - 2800 C by a transient state method, using a newly constructed apparatus; good fit with previously found data in the low temperature range is obtained. A general discussion of the aims of the project is included. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In continuation of the work on elastic properties of carbons, using the greatly improved high temperature equipment, families of curves of the dependence of Young's modulus on temperature and on the heat treatment have been obtained for four basic types of carbons and as far as possible, for a number of special types of commercial carbons. The amplitude dependence of internal friction and dynamic Young's modulus were investigated in the sonic range for a number of types of carbons as made and also neutron irradiated, as well as the temperature dependence of internal friction of the resonance frequency from room down to liquid hydrogen temperature. The presence of a Bordoni peak at 50 K has been found connected with the relaxation of motion of dislocations. Families of curves of the dependence of heat conductivity and electric resistivity on temperature and on the heat treatment have been obtained for four basic types of carbons, using an improved technique. The ''steady'' sinusoidal wave technique for determination of heat diffusivity has been improved in precision and extended in temperature range and data collected for several types of graphitized materials.
