Grains are located in the direction of heat removal.
The grain size is 100-500 μm.
The surface of the rupture site is characterized by a large number of facets, which characterizes material as a sufficiently high plasticity, and characteristic of brittle fracture by metallic luster.

The microstructure of as-cast EN AC-46500 (Fig. 6) consists of primary grains of the α-solid.
In contrast to the thixocasting process, eutectic microconstituent occluded in the α-grains was not observed.

Introduction The self-polarization effect is extremely important for integrated pyroelectric sensor array fabrication, where ferroelectric switching is unemployable and where a large number of small sensor elements should be poled uniformly in an easy way.
Our sputter-deposited films had XRD-coherence lengths (grain sizes) evaluated from the X-ray diffraction peak broadening of about 40 to 60 nm and c/a values of 1.032 to 1.045.
However, domain walls of thin films are pinned in fine grains or even by the space charge field at the bottom electrode.

Fig.2 also show that the shrinkage rate for all the samples reaches to peak value at about 1700 °C, a large number of low-viscosity liquid should is formed, which indicates that the formation of SiAlON has little been affected by h-BN.
There should initiate microcrack in SiAlON/BN composite materials during cooling after sintering, and the cohesion between grains is incremented, and the thermal stress also be erased fowling the microcrack closed when test sample heating.

The samples used for experimental DTA in microwaves have been a homogeneous mixture of Fe2O3+BaCO3 with the follows characteristics: Table 1 The characteristics of the sample heated in microwaves field Sample Characteristics Code Sample Milling Time [ h ] Grain size [ nm ] Pressing Force [ MPa ] Sample Size Height/Diameter [ mm ] HM 0 1120 300 4/12 HM5 5 400 300 4/12 HM20 20 100 300 4/12 The inert material used in experiments was barium ferrite type M sintered in conventional furnace with electrical resistance.
An important observation is the temperature evolution in the inert material without milling time, because this behaviour shows us that will not be necessary to use a planetary ball to mill the homogeneous mixture to reduce his grains size to obtain a easy heating in microwave field.

Beside, most of crystalline grains in the diamond layer have combined into the D-D structure.

Ultrasonic location have the capability to be fine-grained and a high degree of resolution because the speed of ultrasound in air is sufficiently slow to allow the time-of-flight of a signal to be accurately measured[3,4,5].
After collecting data, we aimed at the research of ranging accuracy on the position of different angles as well as different number of reference nodes Fig.2 Average range error contrast figure under different Angle Fig. 2 shows the simulation rendering of mean error when the angle between node under test and reference node is different.
However, with the increase of reference nodes number, the calculation amount of algorithm is becoming more and more large.
Along with the increase of the number of reference nodes, positioning system constantly request.
Therefore, the number of the reference nodes which participate in position calculation increases and positioning accuracy is on the rise.
