In preparing LiNi0.5Mn0.5O2 materials by coprecipitation method, temperature on the properties of materials have great effect, low temperature, crystallization of the material is not very good, the grain size is even, the temperature is too high, so the reunion phenomenon is serious, the electrochemical performances of the materials is relatively large, affect the service life of the battery.

Numbers of surface treatments have been developed to generate protective coatings or surface coating for magnesium alloys [3].
The oxide film with 0.1 g/l of NaVO3 has a relatively smooth surface appearance with fine grains and uniform in structure compared to that of sample with 0.05 g/l of NaVO3.

The heat affected zone (HAZ) region of Monel alloy revealed the grain coarsening in the adjacent area of the weld zone.

The cast microstructure of reformer pipe of Hk40 is consisted of austenite and eutectic in grain boundary of the austenite.
The secondary carbides are small and dispersed at the beginning, which grow up and its number will be reduced as the temperature increasing and the extension of time.

Introduction In production of elements made of glued laminated timber the larger knots are removed from lamellas with the help of mechanical sorting of timber, but even then there are areas of element where relatively large number of small knots can occur, which may negatively affect the strength of the material.

Vibration feeding system as an important type of feeding equipment has played an important role in material handling, and is widely used in the chemical industry, building materials, metallurgy, machinery manufacturing, grain and food processing, feed processing, environmental protection, ceramics and other industries.
We have developed the output proportional amplifier circuit and sensor probe circuit and the sensor housing on the basis of the large number of experiments.

Table 1 Compression mechanical properties of pure aluminum foam Specimen number Inflation pressure（MPa） Relative density Strain ratio(S-1) Yield stress(MPa) 2 0.3 0.271 1000 14 1 0.4 0.271 1600 17 38 0.6 0.282 1900 20 8 0.3 0.289 1000 14.8 3 0.4 0.282 1600 18.5 6 0.6 0.289 1900 21.5 Relevant data of the above comparison tell us that the relative 38 3 strain rate rises 15.79%, the yield strength increased by 7.5%; 1 relative 2 strain rate rose by 60%, the yield strength increased by 21.4%; 6 relative 8 strain rate rose by 90%, the yield strength increased by 45.3%.
Grain Boundary Peak in a Foamed Zn-A1 Eutectoid Alloy.

The grains are coated with an organic material, which provides the bonding and produces a high electrical resistivity.
Fig .2 Cross section of the rotor Fig. 1 Structure of the stator core Rotor Design There are normally two choices of the pole number: 2 or 4 poles, which have both advantages and disadvantages.

Table 1 Mass Ratio of Graphite and Carbonyl Iron Number S1# S2# S3# S4# S5# Carbonyl iron（g） 240 240 240 240 240 Graphite（g） 0 10 15 20 25 A SEM(S4800) was used to observe the microstructure of these samples.
In the cross section, grain carbonyl iron and lamellar graphite are uniformly distributed too.

One may reveal the specific cast structure of these alloys, consisting in solid solution with dendritic segregation, big and heterogeneous grains.
