The γ/γ´ two-phase growth commonly observed at γ interdendritic regions in Ni-base superalloys is known to be the eutectic microstructure. However, it is still unclear whether this is due to a eutectic or peritectic reaction. Directional solidification experiments of the Ni-base superalloy CMSX-10 were performed at low solidification rates in order to induce the coupled growth of γ/γ´ phases and to investigate their growth behavior. The γ and γ´ phases were found to grow simultaneously, maintaining an isothermal interface. Directional solidification experiments in a thin tube (0.8 mm ID) suggest that convection enhances the formation of two phase peritectic growth with a planar interface and the γ/γ´ might be the couped peritectic.

A single-person-house-holder has been increased since 2000s in South Korea, which led to high demands for small and medium-sized new houses requiring municipal architectural review committee consideration. And it has been argued recently that there are many limitations in the review system. Comprehensive expert surveys and interviews were conducted and the results were analyzed using the AHP to explore limitations in B city. The analysis with the data of 27 survey responds found that 'Related ordinance itself', 'Committee members limitation', and 'Absurdity on administrative procedure' are problematic in order of priority. It is also revealed that architects and administrative officials have different thoughts on the seriousness of those. The results of this study are expected to be used as basic data on studies for improving the system.
