Özet
Mechanical behavior of YBa2Cu3O7-x (Y123) superconductors exposed to Sn nanoparticles diffusion is determined by the way of Vickers microhardness (H (v) ) conducted at different applied loads (0.245Na parts per thousand currency signFa parts per thousand currency sign2.940 N). Load dependent microhardness, load independent microhardness, elastic modulus, and yield strength values are estimated from the microhardness curves. Unpredictably, the findings of the H (v) values reveal that the undiffused sample and Sn diffused sample prepared at 500 C-a similar to exhibit reverse indentation size effect (RISE) behavior while the other samples obey indentation size effect (ISE) nature. Further, we extract the load independent (true) microhardness using the Meyer's law, proportional specimen resistance (PSR), elastic/plastic deformation (EPD), Hays-Kendall (HK) approach and indentation-induced cracking (IIC) model, and compare the true hardness with the apparent hardness.
