The formation of secondary phase in the non-equilibrium peritectic reaction was observed by precise transmission electron microscopy analysis. The microstructural evolution and phase selection regularities under different solidification velocities were constructed from the laser resolidification experiments. A new phenomenon involving two-phase coupled growth was firstly detected in the rapidly solidified Ti-Al peritectic alloy. The Ti-45Al-2Cr-2Nb alloy with fully lamellar structure ( a 2+ g ) was taken as an object to investigate the possible preparation of bulky metastable g phase materials based on both adjusting the competing nucleation relation and changing the growth kinetics condition.

Investigating the influences of processing parameters on the C/Si molar ratio of resulted nanosized SiC powders indicated that there was a direct pyrolytic reaction from DMS to SiC as well as the previous proposed two-step reaction. Under the optimized processing conditions, the silicon carbide powders of homogeneous particle size distribution, spherical shape and stoichiometrical C/Si molar ratio are obtained. The silicon carbide particle consists of β-SiC crystallite arranged randomly.

The result indicated that we can get stable homopolymer and copolymer emulsion with uniform size distribution, when the ratio of sodium polyether sulfovinate modified polysiloxane to sodium lauryl sulfate was two, the quantity of the emulsifiers ranged from 6% to 8%, the quantity of initiator ranged from 0.4% to 0.8%, the stirring speed ranged from 200rpm to 250rpm, the polymerization temperature was 80 centigrade degree. As for the copolymer emulsion, the more the TRIS content in the monomers, the larger the water contact angle of their films became, namely, the surface energy of the copolymer films increased with the TRIS content in the monomers. In addition, the glass-transition temperature of the copolymers ranged from high temperature region to low temperature region with the increasing of TRIS content in the monomers.
