0 showed that due to grain growth restriction, grains boundaries increased thus coercivity increased.
As shown in Figures 4(a), 4(b) and 4(c), there is significant grain growth between the Min/Min, Nom/Nom, and Max/Max heat treatment conditions of the 1.
In the samples hot-pressed at 1,350[degrees]C for 1 h under 30 MPa, Vickers hardness remarkably increased to about 2,360 Hv, perhaps due to the high densification and minimization of the grain growth.
In conventional thermal processes, the material must be kept at temperatures as high as 400[degrees]C for approximately 30 min to achieve similar grain growth.
A significant reduction in density values was observed at higher temperatures, a phenomenon probably attributed to the grain growth.
7 shows to enhance the atomic mobility and caused the grain growth to result in a better crystallinity.

Hence, the objective of this study was to evaluate grain growth rates of individual grains at different positions within a spike of bread wheat genotypes.
Although the size of ZrO2 increases, the reaction product ZrO2-Fe3O4-ZnO and ZrO2-Fe3O4-MgO grains play an important role in limiting mass diffusion and movement of grain boundaries, which could be responsible for preventing grain growth of ZrO2 [13-15].
