The number of pores was higher with the gain fraction of grain boundaries.
The porosity was related not only to the number of pores but also to the pore geometry.
The grains in all the three specimens were attached well to the neighbor grains.
A high number of pores were noticeable in the 3 h milled specimen.
The 4 h milled specimen showed relatively a few numbers of pores than the 3 and 5 h specimens.

The analysis on the correlation between yield factors and yield indicated: the correlation between ears number and yield did not reach to significant level (r=0.767, r0.05=0.811); the correlation between grains/ear and yield reached to significant level (r=0.978, r0.01=0.917); and the correlation between 1000 grain weight did not reach to significant level (r=0.669, r0.05=0.811).

This seems to be confirmed by the reduced number of cracks detected near the fracture surface from cross-sectional observations (Fig.5).

This study aims to use a diamond tip to plunge further on the grinding wheel, beyond the point of plastic deformation, to obtain a relation between depth of contact and number of collisions between the diamond and abrasive grains.
The full process is performed in two other positions along the width of the grinding wheel and the average number of grains is evaluated for each depth of contact.
Fig. 5 Signal intensity and number of kinematic edges on the grinding wheel using abrasive grains Type A.
Fig. 6 Signal intensity and number of kinematic edges on the grinding wheel using abrasive grains Type B.
Although it is difficult to classify each peak on the AE signal as a perfect collision between the diamond and a whole grain, it is possible to relate the total collision count to the number of kinematic edges and therefore observe the wear influence over the number of active grains.

Figure 1a shows the number of cycles needed to form a PSB and demonstrates that the number of cycles is the higher the lower the stress amplitudes are.
Fig. 1a Stress amplitude and number of cycles needed to form a PSB.
In addition, the increasing number of grains containing PSBs was observed continuously and is also plotted in Fig. 2.
The other lines in Fig. 2 indicate examples, when 5%, 10%, 30% and 100% of the grains were covered by PSBs at higher numbers of cycles.
Cracks even 50 µm apart from the surface and also interior grain-boundary cracks as well as fragmented internal grain boundaries and dislocation wall structures could be observed [4].

Comparing Fig.3(b) with (c) of the sono-
solidification, it is worth noting that the number
(different solid fractions) of non-equilibrium α-Al
grains increase as the eutectic solidification
proceeded.
3.3 Increase in area fraction of αααα-Al grain
during eutectic solidification
In the sono-solidification of hypereutectic
Al-Si alloy, non-equilibrium α-Al grains increase
as the eutectic solidification proceeded, as
described above.
Comparing Fig.5(a) with Fig5(b), non-equilibrium α-Al grains become more granular and keep on increasing the number as the sono-solidification proceeded.
The profile of silicon content in primary α-Al grains is a concave shape, that is, primary α-Al grains crystallized at higher temperature has the lowest silicon content at the grain center based on the consideration of Fig.6 at ambient pressure.
The Fig.7(b) exhibits that the silicon content in non- equilibrium α-Al grains of Al-18mass%Si alloy solidified with ultrasonic irradiation is higher at each grain center.
(4) Non-equilibrium α-Al grains contain higher silicon content than that in primary α-Al grains of hypoeutectic Al-Si alloy solidified without ultrasonic irradiation.

A
second microstructure parameter is the RB fraction, f, defined as the number of RB divided by the
total number of boundaries.
The crack is allowed to propagate along grain boundaries only.
Instead, a discrete model is used, where nodes are placed in the grains centers and beam elements connect every pair of grains with common boundary.
This assumption is consistent with experimentally observed grain boundary behaviour (e.g
The failed grain boundaries are shown as non-transparent (blue and green in colour).

Furthermore, twinning is highly sensitive to grain size, with finer grain sized samples exhibiting a lower volume fraction of twins [3].
It means that the grain growth of the alloy is sensitive to the annealing temperature but the growth of the recrystallized grains is slight.
Table 1 date of the grain size and hardness of the annealed specimens.
These effects of orientation will be particularly important in non-cubic metals, due to the small number of their slip systems [13].
The strength anisotropy increases with decreasing grain size.
