EFFECT OF NEUTRON IRRADIATION ON THE THERMAL EXPANSION OF CARBON MATERIALS

摘要

The dose dependences of the linear thermal expansion coefficient are examined for various carbon materials irradiated at temperatures between 320 and 2100 K to fluences of (2-3)X10~22 n/cm~2(E>=0.18 MeV). Correlations between the linear thermal expansion coefficient and some physical properties of carbon materials are outlined.
