The phrase "a decrease of the microhardness of" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing changes in the microhardness property of materials.
Example: "The experiment showed a decrease of the microhardness of the alloy after prolonged exposure to high temperatures."
Alternatives: "a reduction in microhardness of" or "a decline in the microhardness of".
The decrease of the microhardness is explained by formation of nanocones as a result of plastic deformation of the mechanically stressed layer, which is characteristic to the SLA stage, as shown in Figure 5. Figure 5 Microhardness of n -Si (111) wafer depending on laser intensity at load on indenter 20 g.
The decrease of the microhardness is explained by formation of nanocones as a result of plastic deformation of the mechanically stressed layer, which is characteristic to the SLA stage, as shown in Figure 5. 5.
They reminded that 5.25% sodium hypochlorite can significantly decrease the microhardness of MTA cement [ 31] which is a reason for using this substance in our pilot study.
In microhardness evaluations of MTA after being exposed to hydrochloric acid it was noted that this solution can significantly decrease the microhardness of MTA which is similar to findings of other investigators [ 16, 21].
Further heating at higher temperatures demonstrated a decrease in microhardness of both kinds of deposits.
The application of antibiotic paste significantly decreased the microhardness of dentin after 1- or 3-month periods, whereas 1-week application did not.
Authors have presumed that by decreasing the microhardness of MTA it could be removed more easily than hard and set cement.
As a consequence, the microhardness of the sample increases by decreasing Ev for a constant overlap rate between two neighbor cladding tracks, similarly, the microhardness also increases by decreasing Ev for a constant laser scanning velocity.
Evaluation of the microhardness showed a correlation between increased ultrasonication times and the microhardness of the MTA samples.
However, the microhardness of the sintered nanocomposites decreased significantly by 9.4%, decreasing to 88.626 from 97.787, when the content of GNPs increased to 0.8 wt%.
