Introduction Due to DSS unique mechanical properties, such as continuous yielding behavior, a lower ratio of yield/tensile strength, superior combination of strength and ductility, good formability, and a higher initial work-hardening rate compared to the other high-strength low-alloy (HSLA) steels with similar chemical composition as well as improved resistance to localized corrosion, particularly pitting, crevice corrosion and stress corrosion cracking, they have received wide application in automotive, ship building and offshore structures construction. [1–5].
The result is a microstructure of roughly 50% austenite and 50% ferrite; although in commercial alloys the ratio may be 40/60. 20µm (a) (b) Fig. 1 Metallographic structure of duplex stainless steel alloy (a. 100× b. 200×) 3.2.

At this time, silicon aluminum oxides in raw material gone through a depolymerization to again polymerization process, and formed a structure which was similar to some natural mineral structure in the crust.
By [6,9,14] know, the existence of heavy metal ions influence chemical components of geopolymer, but less affecte the final product structure.
As a result, the complex geopolymer structure consists of chains, sheet-like and three- dimensional networks made up of various Q unit types of connected SiO4 and AlO4 tetrahedra [21].
Zhang et al. [9] showed very little change in geopolymer structure was observed when these materials were compared to their uncontaminated counterparts.
Geopolymer structure is a "kind of crystal structure" that constitute by the annular molecular chain.

It is seen from fig. 2 and fig. 3 that the experiments of two series have some different changes of solidification structure.
Discussion According to the experimental results, the solidification structure can be refined and equiaxed when ECP is applied to the process of solidification.

When zone temperature T ≥ 1500K, the gas-phase chemistry and soot source terms are calculated.
HACA (H-Abstraction, C2H2-Addition) means that the hydrogen atom desorption from the addition of phenyl acetylene molecules, referred to as "plus acetylene dehydrogenation" mechanism, but this calculation is different from the FM in the detailed model, using literature [4] in the test results, using naphthalene (C10H8, or abbreviated as A2, said aromatic hydrocarbon with two benzene) as the PAH into the representation of the nuclear components during the chemical reaction is as follows: C6H6－H=C6H5 (Dehydrogenation) (3) 2C6H5＋C2H2=C10H8+4HC (Plus acetylene) (4) 1.1.4 PAH growth, rapid polymerization and oxidation Growth in the early stages of PAH, it is mainly planar structure.

Surface modification of nano-silica with silane coupling agent Minhong Xu *, Yongyong Cao and Shunguo Gao Department of Materials Chemistry, Huzhou University, Huzhou, Zhejing, China *Corresponding author: minhongxu@hutc.zj.cn Keywords: Nano-SiO2, surface modification, silane coupling agent, KH-550, KH-570 Abstract: Surface modification of nano-SiO2 was carried out in ethanol solution with two different silane coupling agents, 3-aminopropyltriethoxysilane (KH-550) and 3-methacryloxypropyltrimethoxysilane (KH-570), respectively.
The structure and performance of modified nano-SiO2 were analyzed by infrared spectroscopy, surface hydroxyl number and conductivity.
Characterization.The structure of SiO2 particles was characterized with a NicoleET5700 FTIR instrument. 2g nano-SiO2 in a 200 ml beaker, 25 ml anhydrous ethanol was added, followed by adding 75 mL 20% (w/v) NaCl sodium, the solution was stirred until dispersed evenly.
On the other hand, the reaction of the silane coupling agent and the nano-SiO2 was hindered by the length chain structure of the modifier (KH-550 or KH-570).
