Components can be rapidly produced in large numbers with excellent surface finish and dimensional tolerances compared with, for example, casting and mechanical forming processes.
Figure 1(c) shows association with the original austenite grain boundaries in martensite but previous studies of the martensite starting microstructure have shown more uniform dispersion [13].

Introduction Hydroxyapatite (HA) is usually used for a number of biomedical applications in the forms of granules, blocks, coatings, dense bodies [1-4], for bone augmentation and middle-ear implants [4].
A decrease in grain size to nano scale in dense sintered materials is a desired parameter to enhance the mechanical and biological properties of HA-based bioceramic materials [10].

A large number of alloying elements influences the transformation temperature.
During transformation bainite plates penetrate autenite grains more often and form small packets as shown in Fig. 8 a (red).

Under different experimental conditions, the circumferential crack in surface minute grain punch implementation of the experiment, and the longitudinal cracks may appear in all tests.

During unloading, the stress was unable to hold together the large number of mutually repelling mobile dislocations, which made the dislocations move in opposite directions [12].
Moreover, with the increment of pre-strain, dislocations move along slip planes and easily pile up by the impediment of grain boundaries and twin boundaries.

The high temperature and pressure shock instantaneous produced by blasting is so strong that it makes the rock of crushed zone extreme crushing,it is bad for expanding the blasting volume and improving the blasting efficiency,sometimes even narrow the scope of crushed zone in order to reduce energy consumption.The elastic vibration area is far from the hole so that the stress which decays to less than the strengh of the rock can not crush the rock.The rock in the rupture zone will burst because of a large number of cracks that are produced by blasting,therefore,the rupture zone is the main body of rock blasting.It can improve the quality of blasting by making the cracks of the rupture zone full expansion and extension.
Calculated as stress wave of explosion,the radius of the rupture zone is calculated by the following: (1) In which,: the tensile strength of rock,Mpa;b:scale factor of tangential stress and radial stress, ,:Poisson’s ratio;:stress wave attenuation index about topography and geological conditions of the distance between blasting point and protection,according<< Transportation and Civil Engineering Blasting Engineer Manual >>, values as following: Table 1 The relationship between lithologic and K、 K α Hard rock 50～150 1.3～1.5 medium hardness rock 150～250 1.5～1.8 Soft rock 250～350 1.8～2.0 Table 2 2﹟rock ammonia dynamite performance ps s C [kg/m3] f m 0.83 0.83 0.48 0.57 0.9 1.25 P2:the initial radial stress peak of stress wave,MPa,,:explosive density,kg/m3; D1:detonation velocity, m/s;rb:hole radius,mm;rc:grain radius,mm;n:multiple pressure, n=8~11.

Morphology Analysis of SEM From Fig. 3, we can see that microcrystalline cellulose after carboxylic acid, the microcrystalline cellulose grain decreases significantly and the damage of surface and internal structure appeares, what’s more, morphological structure begins to crush and surface area is also changed, but the fiber rod structure is still kept.
Another important factor is due to the particularity of cellulose micro environment (a large number of hydroxyl, carboxylic acid), and the catalytic oxidation of methyl orange is accelerated; Finally, there also exists the fiber surface adsorption.

The particles are no longer isolated with the ductile aluminum alloy matrix since the number of contacts between TiC particle increases.
[11] Pio, L.Y., Sulaiman, S., Hamouda, A.M. and Ahmad, M.M.H.M, Grain refinement of LM6 Al-Si alloy sand castings to enhance mechanical properties.

The increasing of the particles content implies a higher slurry viscosity: the number of particle-particle interactions increases then the resistance to flow rises.
Two main fractions are observed: a fine fraction of elongated particles of about 1-10 mm and a coarse fraction of irregular grain with size up to 100 mm.

Physical metallurgical transformation consists of dynamical recrystallization, grain growth and dynamic recovery.
For example the temperature data of file outputted by the Fig. 6 Temperature histories of the header, the middle and the tailor of the strip initial iteration read the number of nodes numnp f i rst node of el ement ?
