| Popis: | 1. Experiments have revealed the existence of a low-temperature range of heat evolution for titanium diboride irradiated with neutron fluxes of integral doses 1.20 · 1018 thermal neutrons/cm2 + 1.25 · 1018 fast neutrons/cm2 and 1.46 · 1017 thermal neutrons/cm2 + 1.52 · 1017 fast neutrons/cm2 at temperatures of 115 and 130°K. 2. It is shown that the total amount of heat evolved is much smaller in a material irradiated with a neutron flux without its thermal spectrum than in a material irradiated with the full spectrum. 3. The hypothesis is advanced mat the heat evolution effect observed is linked with the annealing-out of interstitial atoms released from traps such as impurities. |
