We studied on the effects of hot-worm rolling on recrystalized structures and tensile strength in over-aged 7075 A1 alloy, to develop the process for improving properties. It showed more clear effect of the grain refinement with over-aging before plastic deformation. That means, the coarse precipitates from over-aging play a roll as nucleation sites in the course of recrystallization. And on this study, the relations between yield strength and grain size was not satisfied with Hall-Petch equation because of the elongated structure, but the yield strength is proportional to aspect ratio of grains. In TMT process for improving strength and toughness, the worm working is available for increase of those properties than cold working.

Employing a sample of 283, data were analyzed by using the structural equation model of the Lisrel analysis, in addition to cronbach's alpha coefficient for reliability and confirmatory factor analysis for validity. The results of this study was found that a conceptual model for adolescent's conspicuous consumption on clothes was judged to provide acceptable goodness of fit. Specifically, materialism and clothing conformity had a direct effect on conspicuous consumption on clothes, and materialism, hedonic shopping orientation and clothing interests had a indirect effect on conspicuous consumption on clothes. The results indicated that clothing conformity had important influence on conspicuous consumption and its influence on adolescent's conspicuous consumption was mediated by materialism, hedonic shipping orientation and clothing interests.
