| The results of the surface mechanical properties (i.e., hardness and elastic modulus) in the unmodified and radiation-modified As2S3 glass measured about 10 years after 60Co γ-irradiation, using a nanoindentation test with an ultra nano hardness tester (UNHT) were reported. It is indicated that the γ-irradiated g-As2S3 (g- for glassy) with the average energy of 60Co γ-quanta of 1.25 MeV and the accumulated dose of 2.41 MGy exhibits the increased surface hardness and elastic modulus values, compared to the unirradiated material, in the range of 200-1 600 nm indentation depth. In the long-term radiation-induced improvement of the surface mechanical properties in g-As2S3, the broader distribution of the experimental data was detected for the irradiated sample with radiation-induced oxidized layer, compared to the clean sample without the layer that was removed by washing and polishing. |
