Abstract

The structural and phase state of powder samples of compounds Ti3Al and TiAl has been investigated experimentally before and after the action of small doses of gamma irradiation. To study phase and structure parameters, the X-ray diffractometry has been used. It has been established experimentally that after the same conditions of gamma irradiation structural states of these compounds differ. It has been revealed that for compound Ti3Al small doses of gamma irradiation serve stimulators to form radiation-induced states. In the irradiated TiAl sample, a crystal-lattice distortion was observed with the retention of a high crystallinity of the structure and no signs of a special radiation-induced state were revealed.
