| Abstract | ||
| In this study, The calculation of Frenkel pairs generated as a result of irradiation of (Tungsten Carbide – Cobalt 6%) alloys by 25 keV, The value of radiation dose was (6.25×1018 particle / cm2) and the range of the irradiation time between (60-420) sec .The hypothetical irradiation was made using light charge particle electrons .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 irradiation time 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 the hardness of the alloys. | ||
