摘要

Abstract

Due to the interesting properties of Hafnium diboride (HfB2) as a ceramic, it has drawn considerable attention from several researchers. To understand the radiation properties of HfB2 that may be used in the nuclear industry, the interaction of this composite under neutron irradiation was studied. It is obvious that, because HfB2 has Boron, this composite has the potential to absorb neutrons particularly in the range of thermal energy. The ,10,B (n, α) ,7,Li interaction is dominant among other interactions that produce alpha particles. The results revealed that alpha particles have a high fluctuation diagram following a saw-tooth spectrum, for thermal neutron energy which has to be carefully analyzed. If HfB2 intended to be used in fusion facilities, for example; in fusion reactors, its interaction with high neutrons (14 MeV) should be studied. The results for this case showed that, in the wide range of alpha energy, the amount of alpha particle is almost constant so this continuum spectrum is almost flat and there is just a small peak at 2.31 MeV that is belong to the very famous interaction (,10,B (n, α) ,7,Li)..
