Fig. 6 Relative density of specimen prepared under each condition. Relative density is the rate of specimen density and true density of powder material [ 44 ]. Specimen density is obtained using a hydrometer (Shimadzu Corporation, AUX220) based on Archimedes' method. More about this image found in Relative density of specimen prepared under each condition. Relative densit...

Fig. 7 Cross-sectional image at the edge of the specimens. The black region on the right edge of each image is the background. A thin section cut from the cross section of a block-shaped sample is observed using a microscope (Keyence VHX-5000). The layering direction is from the bottom to the top ...
