Sentence examples for a decrease in the grain from inspiring English sources

With this present research work, it is demonstrated that there is an improvement in forgeability and microhardness as well as a decrease in the grain size of the material predeformed by SPD.

The regression analysis revealed that the material deformation was more homogeneous with a decrease in the grain size and an increase in the feature dimensions when the µLSFD process was employed.

The residual stress determined by glancing-angle XRD demonstrates that the deposited TiN films on ion-implanted substrates exhibited reduced compressive stress, from − 3.95 to − 2.41 GPa, which corresponded to a decrease in the grain size of the TiN films.

With a decrease in the grain size down to submicrometer (<1 μm) and nanometer (<100 nm) dimensions, twinning was observed to take place via partial dislocation emission from grain boundaries and grain boundary junctions, which is different from the pole mechanism operating in coarse-grained Cu.

However, based on the SEM and AFM analysis, a decrease in the grain size of the multilayered coatings (Fig. 3b d) was demonstrated compared with the as-deposited CrN coating, which agreed well with calculation results of the grain size shown in Fig. 2b.

The wild type CHA0 and strains CHA631, CHA77, CHA89 caused a decrease in the apparent grain size whereas strains CHA400 and CHA661 caused an increase in apparent grain size due to aggregation.

Welding caused a decrease in the mean grain size, in the hardness and in the corrosion resistance of the age-hardened alloys.

This thus leads to a decrease in the density of grain boundaries in the film.

Here a decrease in the number of pollen grains per flower by up to 57 % was observed.

Vasek and Weng (1988) mentioned that the evolution of inbreeding in flowering plants has commonly been accompanied by a decrease in the number of pollen grains produced per flower.

The simulation also shows that grain boundary migration controls the rate of grain elongation and that the grain elongation affects creep rate parameters: the elongation of grains causes a decrease in the stress exponent from the initial value of 1.0 for equiaxed grains and an increase in the grain size exponent from the initial value of 3.0.
