Sentence examples for hardness determination from inspiring English sources

Characterization and mechanical properties of the surface were investigated using Optical, Scanning electron microscopy, XRD and Emco Dura Scan tester to observe the microstructure, grain size, porosity, phase changes and hardness determination.

In the frame of the present paper, the contact area between the indenter and the specimen during loading and unloading nanoindentation phases are defined through FEM supported calculations, thus enabling the hardness determination after various methods.

The simulation considers two alternative approaches to microstructure evolution and subsequent material hardness determination: one relying on the heating rate dependent austenitisation temperatures (Ac1 and Ac3) governing microstructure transformation kinetics and the other neglecting heating rate dependence.

In order to check the validity of the developed hardness determination procedure, various materials and coatings were tested through nanoindentations and their Vickers HV and indentation hardness HIT were computed and experimentally verified versus the indentation depth, by means of SEM-supported observations of the occurring impressions.

Finally, we propose a methodology to avoid the influence of the roughness and of the porosity on the hardness determination and to model a selected part of the loading curve for the determination of the macrohardness and a parameter representative of the indentation size effect.

The well-polished ceramics were subjected to Vickers indentation (Galileo Microscan, LTF S.p.a., Antegnate, Italy) for hardness (HV) determination.

The coating characterization included optical microscopy and SEM of metallographically prepared cross-sections, hardness measurements, determination of the Young's modulus and phase composition by X-ray diffraction.
