The grain was a bit became small.
When the addition of Fe was greater than 0.6%, the number and size of the impurity which included Fe became greater enough to make the bending condition worse.

., different crystalline fraction and crystallite grain sizes, were obtained by varying the growth parameters.
The peak is shifted to smaller wave numbers as the crystal diameter decreases due to the confinement effects.

These all indicate the coating happened grain abrasion under this condition.
Table. 2 The wear extent of four samples Sample number A B C D Wear before(g) 7.9864 7.8484 7.7803 7.7713 Wear ending(g) 7.9562 7.8007 7.7270 7.7535 Wear extent (g) 0.0302 0.0477 0.0533 0.0178 To sum up the above arguments, the structure stability in the HAZ of the D system (Ti+V+C) is better.

Perceptron model For inequality groups: Is any given normal number, write the one gevin befoe on formr of simultaneous equations : Ya = b Is a N < d matrix, b=[],b>0,n=1,2,...
Powder microscopic image of the grain size analysis boundary integral algorithm.

The ultrafine sized particles disperse in the Ni-P matrix, which in order to improve the surface properties has attracted much attention.[1,2] It is believed that the second phase ceramic particles can enhance the hardness and wear resistance of the Ni-P coatings, due to their grain fining and dispersive strengthening effects[3].

However, supposing the manufacturing processes are not carefully controlled, a number of undesirable phases such as carbides, nitrides and intermetallic compounds may precipitate in the microstructure.
It can be seen that in Fig.1 (a) that the σ phase precipitates on the phase boundaries and grows into the surrounding ferrite (α) grains (white: austenite phase, grey: ferrite phase, black: σ phase).

On both sides of the interface is not smooth, there are a number of AlN grains embedded into the Ni layer.

Having a relatively longer service life, the lower mold can be taken larger grid size to reduce the grid number, with minimum mesh size of 3 mm, ratio of 3, 22427 grids and 5120 nodes.
If the heating temperature is exorbitant, coarse grains, excessive heat or burn of aluminum alloy material will appear, causing the deterioration of the forging performance.

*ARI: The long-term average number of years between the occurrences of a flood.
Conclusions As conclusion, it can be conclude that Sembrong River Dam slightly shows high soil loss where is consist of soft fine grained silty clay material with organic matter, tree roots and decaying timber.

Non-killer crystal defects include stacking faults (l), basal plane dislocations (m), bar stacking faults (n), and grain boundaries (o).
The number of such escapees are very low.
