The flexure strength, fracture toughness, Young’s modulus, and Vickers hardness of the consolidated specimens were...

...E. A. Baxevani; A. E. Giannakopoulos The present paper presents a relation between the vickers hardness HV and the loading stiffness C of instrumented vickers indentation of metal substrates. The relation is based on the fact that the nonaxisymmetry of the plastic deformation of the vickers...
