Copper Effect

The role of copper additions to GOES has not been fully understood yet. Several mechanisms have been proposed: stabilization of austenite during hot rolling in two phase α+γ region, precipitation of ε - Cu, dissolution and re-precipitation of Cu-bearing sulfides, segregation of copper at grain boundaries and support of deformation by twinning and shear during cold rolling.This paper deals with minor phase evaluation in Cu–bearing GOES after following manufacturing steps: a) the first cold rolling and decarburization annealing at 820 °C, b) the second cold rolling followed by a slow laboratory heating to the temperature of primary recrystallization (620°C). Microstructure analysis was carried out using EBSD and TEM techniques. Results of experimental studies were compared with Thermocalc predictions of the copper effect on equilibrium phases in GOES.

Processing Steps

The magnetic properties of electrical steels are related to the microstructure and texture of the final processed steel. There is an interplay and interaction of the microstructure and texture between the various processing steps. The ongoing structural changes at final annealing of the cold rolled material depend sensitively on the deformation structure after the cold rolling with high deformation. In this paper, we will study in detail the role of the microstructure of the hot strip on the deformation structure after cold rolling with high deformation.

<em>This study aims to determine the description and influence of human capital, creativity and organizational performance at Krisnadwipayana University.  The research method used in this study using quantitative methods can be interpreted as a research method based on the philosophy of positivism. Researchers who use a quantitative approach will test a theory by detailing specific hypotheses, then collect data to support or refute these hypotheses. The approach to be used in this research is a quantitative analysis approach based on statistical information. This study shows that the effect of human capital on creativity has a significant effect, the effect of human capital based on the test results has a significant effect on organizational performance, the effect of creativity based on the test results has a significant effect on organizational performance, and the effect of human capital through creativity does not affect organizational performance. because the existence of creativity as a mediating variable does not make the role of human capital increase in organizational performance.</em>

AbstractThe possibility that primary recrystallization textures are influenced by local inhomogeneities of deformation induced in the regions of grain boundaries has been confirmed by comparing the cold rolling and the annealing textures of polycrystalline pure irons which were different in the grain size prior to cold rolling. Analyses were made for the effects of deformation on crystals, namely storage of lattice strain and orientation spread, with application of X-ray diffraction techniques, in order to elucidate the role of in homogeneities of deformation on recrystallization texture formation. Apparent correspondence was found between the orientation dependence of stored strain energy and the textural change on recrystallization. This is a scribed to oriented nucleation in high energy blocks, in the case of originally large-grain material in which the effects of inhomogeneities of deformation are small. But discrepancies arise on this basis in originally small - grain material in which the effects of inhomogeneities of deformation are thought to be considerable. The discrepancy is inferred to arise as an effect of local inhomogeneities of deformation, from the change in the trend of rotational orientation spreads from, a stable orientation and the extent of development of potential nuclei of recrystallization at high energy blocks in the orientation spreads. The change is considered to give rise to the variation in amount of microstrain distribution, which is expressed in recovery characteristics of lattice strains and in the dependence of microstrains on the column length as analyzed by following the procedure of Warren-Averbach.
