Sentence examples for rate of hardness from inspiring English sources

It is shown that the micropolar parameters contribute to describe the characteristic of ISE at different scales, where the material length scale regulates the rate of hardness change at large indentation depth and the value of micropolar shear module restrains the upper limit of hardness at low indentation depth.

Depth sensing instrumented indentation experiments performed at different loading rates on specimens revealed an increasing rate-sensitivity of hardness, which concerns with a significantly small activation volume for plastic flow.

The results shown that, the reducing rate of Vickers hardness of cement paste samples immersed in solutions containing different sulfate salts were generally sequenced as Na2SO4 ≈ K2SO4 > MgSO4 > (NH4 2SO4.

Depth-sensing instrumented indentation experiments performed at loading rates spanning three orders of magnitude on specimens with the higher density of twins (twin lamellae width ∼20 nm) revealed an up to sevenfold increase in rate-sensitivity of hardness compared to an essentially twin-free pure Cu of the same grain size.

The level of agreement between the subjective rating of ground hardness and the objectively measured hardness is presented in Figure 2. Figure 1 Box-and-whisker plot representing the hardness values for the four categories of subjective rating.

The results show that the wear rate of solid solution TaCxNy films is mainly governed by hardness and the ratio of hardness (H) and elastic modulus (E).

Artist pencils come in a range of hardness and softness.

The model is applied in an analysis of the isothermal rates of recovery of hardness upon annealing of commercial purity aluminum at temperatures between 140 and 220 °C of samples cold rolled to strains 2 and 4.

Further increase in oxygen flow rate caused a decrease of hardness, adhesion and wear resistance, while together with the increase of friction coefficient.

The results show that the removal rate is mainly a function of hardness, which decreases nonlinearly with hardness.
