In the current work, the load-independent Vickers hardness values of CoFe2O4 doped Y123 compounds were investigated by using six mechanical modeling approaches namely law of Meyer Law, proportional sample resistance (PSR), elastic/plastic deformation (EPD), proportional sample resistance (PSR), Hays-Kendall (HK) and indentation induced cracking (IIC). Solid state reaction and the sol gel methods were preferred to produce samples undoped and CoFe2O4 doped. Vickers microhardness tests were conducted on samples with loads of F=0.249, 0.450, 0.980, 1.990, and 2.940 N in order to ascertain the influence of CoFe2O4 particles on the general mechanical properties of the Y123 matrix. While the HK approach was the most suitable model for samples exhibiting ISE behavior, the IIC model was determined as the most successful model for samples exhibiting RISE behavior.
