The alloy should require improving thermal stability of grain structure as well as a finer grain size for the industrial application.
The lower stress should be related to finer grain size.
Change in the grain size implies strain induced grain growth though relation to grain boundary sliding is not confirmed.

Grain refinement has been achieved by severe rolling in all of samples to grain sizes less than 10µm, especially 4.6 and 4.8µm in F1 and F2, respectively.

This paper studies the reheating temperature, deformation temperature, the amount of deformation, the influence that the average pass deformation quantity and number of deformation passes of austenite recrystallization region on Deformed Austenite recrystallization percentage and austenite grain size, to obtain reheating temperature,deformation temperature, the amount of deformation and the average pass deformation amount of austenite recrystallization region of the desired austenite structure[1].
By the experimental results, under the same heating time, when the heating temperature is 1250 ℃, steel austenitic grain average cross-sectional length significantly increased, and austenite grains significantly roughened.
When the average pass deformation greater than 20%, the austenite grain size will be reduced.
When the average pass deformation is greater than 20%, the austenite grain size decreased.
Effect of Zirconium additions on Austenite grain coarsening of C-Mn and microalloy steels.

The average dimensions of grains were 50nm and had high purity of 99.99%.
Nano-SiC grains must be rinsed before being put in the plating solution.
It could be clearly seen that the microstructure of the composite coating is superior to the common coating for the effect of nano-SiC grains on grain refining.
For another thing, the nano grains as the new growing point of crystal nucleus can decrease the increasing speed of crystal grain and results to the grain refining in the coatings(as is shown in Fig.1b), which improves the mechanical property of material further.
The reason lies in that when the number of nano particle begins to increase, the absorbed probability between particle and the surface of matrix will rise and the jogged amount into coatings also increases.

The elastic and consequently plastic deformations occur at the engagement of grains.
The friction of grain and material likewise the friction of elementary chip and grain acts simultaneously.
The friction on the flank of grinding grains exert effort to lengthen the grains in surface layer of workpiece, thus the workpiece surface expands.
The grains of ground surface deform nearly in the direction of chip flow.
The grinding wheels with microcrystalline grains - SG (usually 30% grains SG, the rest is the white corundum) reveal in a number of cases residual stress of pressure character or low tensile residual stress in surface.

People always hope to get the most ideal results with least test number in the development of new material.
In the preparation stage, the grain abnormal growth and the sintered loose microstructure will reduce the mechanical properties of materials.
If the sintering temperature is too low, the sintered body can't fully densified and otherwise the grain growth is serious.
When the duration time is too short, the material will not be fully densified and otherwise the grains will grow seriously.
The mechanical property table is consisted of the basic information such as serial number and volume fraction of the matrix, additive, auxiliary phase and binder phase, the serial number of sintering and preparation and the mechanical properties of the ceramic cutting tools.

However, only a limited number of studies on the prediction of the microstructure evolution of magnesium alloys using the CA method are available.
The orientation of each primary grain was randomly set at an angle within the range of 0°to 180°.
The colored regions denote the R-grains, white regions refer to the deformed matrix, and black lines represent the grain boundaries.
The grains, including the R-grains and deformed matrix, were vertically compressed and elongated normal to the compression direction with the continuous deformation, and the grain boundaries evidently become elongated.
Considering that the nucleation of recrystallization is supposed to happen at grain boundary only, the elongated grain boundary should affect the kinetics of RX and simulated mean grain size.

Introduction The biomimetic synthesis route to forming complex functional materials [1] has recently gained prominent success in a number of areas [2-4].
To investigate the electrical connectivity of the grains within the YBCO powder, hysteresis loops were measured before and after the material was ground to separate the grains.
The addition of NaCl is the key to the appearance of platelike grains.
This value expresses the average grain connectivity within the sample.
In the dextran-mediated sample, the closely-aligned clusters of grains allow an intergranular current to pass, while in the chitosan-mediated sample, no such grain alignment exists, so individual grains remain electrically isolated.

AZ grain is produced by mixing alumina grains with zirconia grains of 30%wt., which is about 1300 in knoop hardness [4].
And the stock removal with AZ grain is larger than that with WA grain that is similar to that with GC grain.
That is, the interference intensity of GC grain is larger than of WA grain because of higher hardness of GC grain.
AZ grain acts on the workpiece surface stronger than WA grain, as the result that AZ grain including zirconia abrasive is softer than WA grain but its specific gravity is larger than that of WA grain.
The number of acting abrasive grain on the workpiece surface is estimated to be proportional to the abrasive concentration, but stock removal at 30%wt. is remarkably larger than those at other concentrations.

Nucleation rate and number of precipitates in V and Nb-microalloyed steels Sebastián F.
The number of precipitates was calculated by integration of the nucleation rate expression.
The interaction of these two phenomena has been widely studied by a number of researchers, who have considered different variables such as the steel composition, strain, strain rate, austenite grain size and deformation temperature, among others.
On the other hand, the integration of equation (1) would give the number of precipitates per unit of volume (N).
Precipitate number vs. time.

Meanwhile, the crystalline grain had a uniformity distribution, and the grain size was about 9.5~10 grade.
When the tempering temperature rose continuously to 640℃, a large number of supersaturated precipitation carbides happened along the grain boundaries, and began to gather and grow forming black network microstructure, as shown in Figure 4(c).
The most numerous of these precipitates were needle-shaped type, while a smaller number of precipitates were club-shaped type.
On the other hand, yield strength of HSLA steels has reached 780MPa [2], which were contributed to the large number of carbide precipitation distributed finely and uniformity.
Consequently, the reduction in the number of M3C carbides leads to an improvement in the fracture toughness [6].
