الملخص الإنجليزي

In this study, the calculation of Frenkel pairs generated as a result of irradiation of (Tungsten Carbide – Cobalt 6%) alloys to different ratios of cobalt.The value of radiation dose was (1×1015 particles / cm2) and the irradiation time (120) sec .The hypothetical irradiation was made using light charge particle electrons (the range of energy of electron between (1-3) MeV) .A special program was written in "Q-Basic" to obtain the theoretical results.

A ccording to this study, it was found that the increasing of the ratio of cobalt causes increase of Frenkel pairs (Interstitial – Vacancy) generated by light charged particles.

These Frenkel pairs are generating dislocations and deformations in crystal lattice which in turn lead to an increase in the hardness of the alloys.

And according to the energy of electrons it was found that the increasing of incident energy of electrons causes decrease of Frenkel pairs lead to a decrease in the hardness of the alloys duo to recombination of Interstitial – Vacancies.
