In addition, boron can promote martensite transformation, and can produce fine-grain strengthening [5].

A point of interest in composites is their ability to transfer stresses across the interface, properties that is related to a complex combination of factors such as surface energy of the reinforcing phase, adhesion strength, number of stratified layers, fiber orientation with respect to the external action.
When crack spreads in composites, it need to overcome resistance to through grain boundaries in the matrix, and then crack extends along fiber interface and overcomes the interfacial shear resistance to make the fibers debond, fracture and pull-out.

The cellular composites used in the present study are manufactured from glass foam granules with the grain-size fraction of 12 mm supplied by Dennert Poraver GmbH, Germany.
Specimens tested at 1 Hz and at 20 Hz test frequency fail after approximately the same number of cycles.

INTRODUCTION A severe plastic deformation technique called equal channel angular extrusion (ECAE), first developed by Segal in 1981 in the former Soviet Union [1, 2] is an innovative technique that allows the improvement of mechanical behavior in materials by grain refinement.
Five numbered nodes were randomly marked onto the specimen, representing different locations in deformation [6].

Fig. 7 Flow charts (host) left and (slave) right Communication Protocol Between host and slave communication must be according to certain communication protocol, specific communication is as follows: After power on, and from the host machine serial port baud rate is 19200bit / s, from the machine every second to host transmits the monitoring data, the communication data format(table 1): Table 1: Communication protocol prefix code serial number (8bit) Humidy (16bit) Temperature (16bit) Control data(8bit) End code a N integer decimal integer decimal C z There into "C" is the host sends the control signal; the signal is set by the user from the machine temperature data and transmitted the actual temperature data comparing the generated, used to control the output from the machine actuator.
Analysis of China's food grain problem[J].

It has been successfully obtained a number of antihypertensive peptides from food proteins, such as fish and shellfish, soy, casein, corn, distillers grains and so on [4-6] .

As a result, the selection of a solid solution of a large number of dispersed carbides on the basis of the alloying components, ie is aging.
The microstructure of the hardened surface of the specimen is a fine-grained martensitic structure with dispersed insoluble inclusions of carbides and nitrides (Figure 2).

Induction tempering has been researched deeply by vast number of domestic and foreign scholars.
Figure 6 shows the microstructure of Q690 steel after quenching, you can see that there are large amount of lamellar structure in the austenite grain.

Heterogeneous volume nucleation is employed to achieve fine-grained glass-ceramic and certain nucleating aids, such as TiO2, ZrO2, and P2O3 [5].
The results shown in Fig. 2 illustrate that the number of crystals is directly related to the amount of ZrO2 added, while the size of the crystal is indirectly related to the amount of ZrO2.

There are a number of TPE categories including styrenic block copolymer, multi-block copolymers (i.e., copolyester, thermoplastic polyurethane, and thermoplastic polyamide), and TPE based on thermoplastic/elastomer blend and alloy (i.e., thermoplastic polyolefin and thermoplastic vulcanizate).
This confirms the invention of novel TPE material based on MNR/COPE blend with outstanding elastic and heat resistant properties as well as fine grain dual co-continuous phase morphology.
