Changes in surface structure and mechanical properties were evaluated based on measurements of the compressive stress, depth of layer, electron probe microanalysis, Raman spectroscopy, hardness, and coaxial double-ring flexural strength after sub-T_g post-annealing at various temperatures and times.
