The elastic modulus of a nuclear graphite was measured in the range from room temperature to 1400Β°C by the ultrasonic pulse echo method. Little or no change in the elastic modulus was observed up to 450Β°C. Above XWC, however, it increased almost linearly with increasing temperature. The fractional i
This paper describes the performance characteristics of a new test apparatus and the measured results using the apparatus. It has been developed on the basis of Harmathy's curve-fitting method to measure, in a short time, the physical properties of the nonmetallic materials for a cryogenic storage t
An apparatus for measuring the integral thermal expansions at cryogenic temperatures is described. The thermal expansions are given for a number of commercial epoxy resins, commercial polyester resins and inorganic cements. A method to reduce the thermal expansion of the resins by the use of quartz
