These very fine particles, by virtue of their pinning effects, play a key role in improving several properties of aluminum alloys by retarding recrystallization and grain growth.
Experimental Procedures A chemical composition of a material investigated is given in table 1.The alloy was melted and cast into a steel mould.
Transverse longitudinal sections of each material were prepared and electrolytically etched in Burker's solution.

Another problem is that the o-aminothiophenol starting material could be oxidized to 2,2’-disulfanediyldianiline in the air.
TLC monitoring showed that all of the starting material was consumed within 1 min, indicating that the reduction of the disulfide bond and the subsequent reactions happened in high reaction rates.

Research on product design process driven by Customer Value Theory Chengye Zhang1,a, Runhua Tan1,b, Guozhong Cao1,c 1National Technological Innovation Method and Tool Engineering Research Center, Hebei University of Technology, Tianjin, China ajlau0431@163.com, brhtan@hebut.edu.cn, ccaoguozhong@hebut.edu.cn Key words: customer value, product design, process model, value design Abstract.
(2) The embodiment of CV not only lies in product function design, but in non-functional forms such as material, color, process, service and etc.
After function structure built in accordance with the former value chain, some CV elements failed to embody in function structure, such as material, ergonomic elements, appearance, etc, can be taken into account in subsequent design phase.
