The strain is affected by substitutions in the structure and these results provide a starting point for comparison of the resulting mechanical properties.
An assessment of the properties of different bone types is required in order to ascertain whether differences are present, which may be exploited in bone replacement applications.
The relationship between mechanical properties and microstructure is thus a key focus of the current work.
In order to retain elastic properties in the material, the use of a less crystalline structure can allow bone to be produced which is less brittle.
Conclusion The study has shown that hydroxyapatite produced from the crocodile bone exhibits properties which are ideal for bone graft applications; this is seen particularly in the high porosity observed, and the low crystallinity.

On this basis, the performance of the device is investigated, and the experimental research on the viscoelastic property of sponge material is carried out using the device.
Introduction In daily life femoral fracture caused by accidental falls is one of the important issues affecting the health of the elderly.
In the development of hip protector, sponge material is usually used to play buffer role, and the viscosity coefficient and elastic coefficient of sponge material are the key factors to absorb energy and to cushion impact.
When the mass m is given a displacement x on the equilibrium position in downward direction, there will produce a force on the mass, the mechanical model is shown in Fig. 1 (b).
However, the viscidity coefficient of sponge is related to the many factors such as density, hardness, composition and structure of the material, so hardness is only an influence factor.

The structural, morphological and magnetic properties of the powders were investigated.
Another factor that affects the magnetic properties of the sample is a possible contamination of the sample with carbon from the mould and punches of the SPS equipment.

Among the innumerous combinations studied, addition of particulate and short fiber ceramic reinforcement to an aluminum alloy matrix has obtained good results, with improvements in tensile strength for SiCp [1,2] and in tribological characteristics for carbon [3], and has great potential nano carbon for improving electrical and mechanical properties in composites [4].
The stirring conditions (position, speed, temperature) and the size of the reinforcement play an important role in the final characteristics of the composite [9], as the turbulence provided by the paddle is responsible for the rupture of the dendritic arms, affecting the fluid viscosity, and still, the dispersion of reinforcement becomes difficult as the particulate size decreases [10].
Besides, stirring speed of 1500rpm was enough to disperse CNF through the A356 matrix, but it had to be raised up to 2500 rpm to properly mix the SiC particles, due to increase in the viscosity of the slurry occurring during the process; z Keeping the solid fraction of the metal slurry between 10% and 20% during stirring is an important factor as it affects the dispersion of the reinforcement through the matrix, especially in the case of CNF.

The results show possibility to fast fabrication functional sensor in customer ceramic SMD package with base 9x9 mm with twice reduced power consumption and improving mechanical properties compare with classical metal-glass microelectronic packages using before for such type sensors.
The improvement of the situation with MIS capacitor-type sensors is seen in the adaptation of laser micromilling technology already used for the manufacture of metal oxide sensors in form-factor of SMD package and described in [11–13].
The conversion to a technology there are microheater integrated in a single technological cycle with package will also significantly improve the mechanical stability of the sensor performance, saving sensor design from adhesive joints that are susceptible to destruction during long-term exposure to corrosive gases and high temperatures typical for use in applications for the detection of sub-ppb gas concentrations H2S [14], C2H6S [15] NH3 [16], NO2 [17].
The flexible technology used in our work allows to continue to improve the MIS sensors in directions of changing geometric dimensions (affecting the capacitance of the MIS structure [18]) and gas sensitivity associated with the temperature conditions of operation (acceleration or stopped physical adsorption of gases [19]).

However, the materials for photolithographic process are required with optimally thermal, optical and mechanical properties on barrier ribs in PDP.
The refractive index among the many properties is important factors to reduce the processing steps and obtain the uniform pattern.
From our results, the thermal and optical properties should be correlated to the glass structure with the SiO2/B2O3 ratio.

The results indicate that, laser treated zones of three roll samples consist of melting zone, phase transformation zone and heat affected zone.
Nowadays there are some reports correlated with laser surface modification [6-8], but most of these reports seems to be related to changing one or two factors among the parameters of laser power, spot size, laser absorptivity of materials, laser moving speed, the degree of spot overlap, and the physical and chemical properties of materials etc., little work was conducted about tempering effect on their microstructure and hardness profiles.
Namely the high speed steel has smallest laser affected zone, the adamite steel has the bigger measurement than the high speed steel, and the indefinite chilled cast iron has the biggest diameter and depth of laser beam affected zone.
It seems to be quite likely that, the microstructural factors, such as the type and the volume percentage of carbide, characteristic of matrix, and with or without graphite, have strong influence upon heat conductivity of the samples during laser treatment [9].
Fig.2 Microstructures of laser treated sections for (a) adamite steel, (b) indefinite chilled cast iron and (c) high speed steel The purpose of laser beam microstructural modification is to enhance expectancy of roll materials through improvement of its mechanical properties, such as the hardness, wear-resistance and the anti-corrosion ability.
