ABSTRACT

The frequency of development contemporary technologies is strongly connected to the
creation of new composite materials with multi-functional application. They should be
characterised with all necessary complex properties for functioning in extreme
conditions. The radiation materials science has one of the important segments among
the huge spectrum in materials science. There is much interest in above mentioned
materials in nuclear technologies. In particular, there are increased requirements in keysegments
in nuclear reactors (under high-loading and high temperatures) working in
extreme conditions. Accordingly, investigations for creating radiation-resistant and
radioprotective materials (protecting from neutron and gamma radiation) are more
active day after day.

Accordingly, it is actual to create composite materials having the optimal ratio mixtures
of constituents, which can produce stable physical-chemical and radiation-resistant
properties and characterized with abilities of inactivated absorption of various types of
neutron and gamma irradiation. In the paper the results of optimization of Me–Gd and
Me-B containing composition for desired properties of developed materials and
preliminary experimental results are discussed.
