Phases stability in alloys during irradiation

It is noted, that X-ray-structural researches of phases transformation of metals and alloys have been carrying out in Inst. of Nuclear Physics of National Nuclear Center of Republic of Kazakstan from the beginning of 1970. It were got new data about crystal structure stability of intermetallic compounds with complete regulated lattice of crystallographic classes D 03, D 019, D 81-3 under irradiation by neutron within wide range of fluences, protons and alpha-particles. It was made conclusion, that main result of inter-metalloids with D 81-3 structure and regulated location of atoms irradiation by cascade-forming particles are both the new phase formation or the phase with distinguish from matrix content of components. Mathematical model of separation of different kind of atoms on cascade and thermal stages of radiation damages is carried out.Generation of collision in the field of cascade is mathematically grounded. It is shown, that samples after special radiation and thermal treatment have high technological plasticity. It known, that it is practically impossible producing of compounds with similarly properties by usual technological ways without use complete power-consuming operations
