That was to say, when the abrasive density was in certain circumstances the quality of machined surface was better because of the smaller abrasive size and the bigger abrasive number.

Furthermore, the cracking susceptibility of ductility-dip crack in the reheated weld metal could be much improved by adding 0.01-0.02mass%La to the weld metal due to the desegregation of impurity elements of P and S to grain boundary by the scavenging effect of La [2].
It follows that plastic strain in the weld metal accumulates with increasing the number of weld passes.

A number of theoretical studies have suggested that the smallest single-walled nanotubes might have Young's modulus as high as 5 TPa [3].
However, it was demonstrated that SWNTs are ideal additives for use as grain boundary stabilizers.

TiAl intermetallic alloy contained duplex microstructure consisting lamellar colonies (TiAl+Ti3Al) and gamma grain (TiAl).
In Nf (number of cycles to failure) = 107, the relation between film thickness, fatigue strength, and fracture mechanism is schematically shown in Fig. 9.

In addition, through observing the failure cross-section, the specimen's fracture surface becomes coarse grain in tensile test.
Table 2 Torsion angle Fig. 6 Theoretical and numerical results for the history of elastic core during torsion In Fig, 6, the numbers from 1 to 7 correspond to the torsion angle are listed in Table 2.

Another reason may be preferential adsorption on different surfaces and the number of adsorption sites on the different surfaces.
The roughness increased with increasing film thickness as on films grown on glass substrate by SILAR and or by chemical bath deposition (CBD)-method.[8,10] From the AFM images it was observed that the PbS grain sizes are much smaller than the 1 µm found in thicker PbS films by CBD [4].

Together with treatment time, the rod-shaped crystal was longer and the number of rod-shaped crystals was increased.
From SEM observation, sintered HA grains were polyhedral shape without specific crystal shape (Fig. 3 (A)).

Consequently, the number of tunnels built in water-rich stratum is gradually increased.
The strata that tunnel passes through are gneissic granite with coarse-grained structure and developed joints.
