Abstract

Zircaloy-2 has been used as fuel element cladding material in both light and heavy water power reactors. The aims of the experiment are to study the kinetics of precipitate coarsening during isothermal a-annealing and to characterize the nucleation and growth of precipitate affected by the variations of cold work and heat treatment. The results of the experiment show that all specimens annealed at 650°C have the average precipitate diameter less than 0.1 um whereas those at 750°C have the average size larger than 0.1 .tm except for one annealed for less than 5 hours. The average size of precipitates is 0.07 um for specimens deformed before 0-quenching and 0.168 .tm for specimens deformed after 0-quenching. The deformed specimens after 13-quenching have more homogeneous size distribution than that of undeformed specimens and specimens deformed before 0-quenching. The kinetics of precipitate coarsening depends on the changes in annealing temperature and time, and cooling rate from the 0-phase region. The nucleation and growth of precipitates have been influenced by the variations of cold work and heat treatment.

Abstract

The development of popular culture lately has an impact on local culture which is starting to be  abandoned, especially by the younger generation. Like kesenian Kubro in Ngasinan Village,  Purworejo, which was abandoned because there was no longer public enthusiasm for that art.  Kubro in Ngasinan Village has been preserved again by Grup Kesenian Kubro Tujuh Bidadari by  combining Kubro with dangdut rhythms to suit the tastes of the community. This effort is a big  thing in preserving local culture. Especially with the involvement of children who are the nation's  next generation in this effort. Thus, Kubro can be a representation of nationalism through regional  arts that are adapted to the times without losing the identity of the art. In this study, visual and  non-visual signs that represent nationalism will be analyzed. The method used in this study is a  qualitative descriptive method with a semiological approach. Based on the results of the analysis,  there are representations of nationalism found in dance moves, the costumes of dancers, and  Kubro’s song lyrics in Purworejo Regency. Based on the results of the analysis, it is hoped that the  main purpose of this art as an effort to preserve a local culture that represents nationalism as well  as entertainment for the community can be fulfilled.
