Titanium and molybdenum were added to refine the grains.
And with the increase of number and size on bulk martensite, the strength of the steel became strengthening.

Therefore, based on the experimentally measured data, a number of research groups have made efforts to develop constitutive equations to describe the hot deformation behaviors of metals and alloys.
This is because that high temperatures and low strain rates provide longer time for energy accumulation, growth of dynamically recrystallized grains and dislocation annihilation.

The section of the existing wall panel But designs of fast-mounted buildings have a number of essential shortcomings: Big body weight of a design; Conservatism (doesn't reflect tendencies of development of materials and designs); The low heattechnical characteristics caused by existence of the cold bridge; Architectural plainness; High logistic expenses.
Investigation of carboxylate plasticizer modification potential in modified fine-grained concrete mixes// Magazine of civil engineering. 2012. № 8 (34).

The hardness increases with the presence of the second phase (inter-metallic) and the decreasing size of the grain [9].

A large number of uses for this waste have been reported in literature by authors such as [13,17,14,27,12,1,5,11].
In a micrometer scale, the particles begin to come together through the formation of necks between the contact regions, which later will be grain boundaries.

The resulting wafers turn out to have a less well organized multicrystalline structure made up of regions of single-crystal silicon separated by grain boundaries.
Although crystal-silicon cells dominate the current solar model marketplace, a number of thin film technologies are beginning to receive considerably research and develop and takes the advantages of crystal-silicon in terms of costs and temperature tolerance.

Even grain size of Ag3Sn is hard to be developed.
Acknowledgment The authors would like express their appreciation to National Science Council of the Republic of China, Taiwan, for financially supporting this research under Contract Numbers NSC99-2221-E-214-012 and NSC100-2221-E-214-034.

Coir pith has a lignocellulose nature and it composed of 2-3% short fibers (up to 2 cm) and cork (with particles from grain size to powder size).

Larger numbers of stalks used as building materials can not only handle stalks for increasing farmers' income, but also provide plenty of construction raw materials.
