Text Experimental Procedure Testing material.
The commercialized aluminum die-casting JIS (Japanese Industrial Standards) ADC12 is used as experiment materials.
At the same time, keeping the die in high-temperature, the die material strength will be declined, and die service life will be decreased.

Experiment Raw Materials.
This is mainly due to the fact that the rubber particles themselves are non-absorbent polymer materials, effectively extending and cutting off the water seepage channels in the concrete, making the capillary pores more tortuous and dispersed, increasing the penetration difficulty and improving the impermeability.

Although the materials are subjected to high external force loads in such systems, but they do not undergo volume plastic deformation which is characteristic to metal forming processes.
Materials and Methods Both low carbon and high carbon steel wires were chosen as objects for investigation.
The microstructure and properties of this layer are different as compared with material in bulk.

Cobaltbase alloys have been traditionally used as hardfacing materials, owing to their high corrosion resistance and superior wear resistance under sliding conditions [4, 5, and 6].

One of the best ways to improve the fuel efficiency is to decrease weight, and magnesium is heavily advertised as an appropriate material to achieve significant weight savings.
Experimental Procedure Materials.Alloys of the nominal composition given in Table 1 were prepared as given in ref [9], with alloys containing calcium and rare earths prepared from > 98.5% purity Ca (Merck) and MEL  Nd hardener.
Creep curves show the compression as a function of time, the compression after 100 h; the creep rate in the last minutes was used as a measure to compare the materials.

However, the resistivity of BT material is 2 at room temperature, that's to say, its conductivity is relatively high [16], it's no doubt that the value of increased dramatically at lower frequency.
The deviation behavior may be due to omitting conductivity of BT materials.
