The design on this purple glass bottle is a potted flower. Infrared light images show light refraction at the flower and soil areas. There is a contrast between the petal and the rim in these images. These results indicate that different materials were used in these parts. UV–light fluorescence images show weak fluorescence at the leaves and the stem. The glass of this bottle contains Pb, Si, and K as the main components and minor components of Mn, Fe, Na, and Al, as revealed by SEM–EDS analysis. The glass composition is not homogeneous as a result of the manufacturing process. The Si species measured by XRF is SiO2 and Pb is in the form of Pb3O4 according to X–ray diffraction measurement. Measurements of the decorated area indicate that Cu–Zn alloy is used in the area of the soil in the flowerpot, and SnO and SnO2 are corrosion products that exist on the surface of Sn thin film. The peak at 390 nm on the reflection spectrum corresponds to the purple color of this glass bottle. The results of XAFS measurement reveal that the oxidation state of Mn is a mixture of +2 and +3, that of Fe is +3, and that of Pb is +2.

And, in dipping experiments of Cu wire and Cu plate into molten Al, the formation reactions between solid Cu and molten Al were also investigated. A piece of Cu wire was put into a crucible, and Al powder was filled around the Cu wire. The crucible was inserted in a quartz tube, and was vacuum-sealed with 10-3Pa vacuum degree. The capsule was kept at 800-1000°C for 0-90 min. using an electric furnace. After the holding time, the cross-sections were observed by an optical microscope and SEM-EDX. Additionally, the dipping experiment of Cu plates into molten Al were also investigated by same method as Cu wire experiment. From the quenching of Cu/Al premixed compacts during the combustion synthesis, Cu3Al formation reaction between Cu particles and molten Al could be observed. The formation reaction was also found in the dipping experiments of Cu wire and Cu plate into molten Al. However, the formation rate and the composition of Cu3Al synthesized was depend on the contact surface shape between Solid Cu and molten Al. Furthermore, kinetics equations were derived for the Cu3Al formation reaction.

The drop tube and electromagnetic levitation pro - cesses, which are types of containerless processes, enable solidiﬁcation melt without using a container. This would avoid heteroge neous nucleation induced by the container walls, thus obtaining undercooling conditions. The abovementioned processes have been used to study the undercooling solidiﬁcation and metastable phase formation of the melt. Metastable miscibility gap is observed in the Fe ︲ Cu binary alloy; however, metastable phase formation in the wide composition range used by the drop tube process has never been reported. In this study, we obtained samples of Fe ︲ Cu binary alloy using a drop tube apparatus with a free fall length of 2 . 5 m and an electromagnetic levitation apparatus. In addition, we aimed to examine the effectiveness of the containerless process for microstructure formation of the Fe ︲ Cu binary alloy based on undercooling solidification. The results of the SEM and EDS analyses showed that the minor liquid phase, Fe or Cu, finely dispersed in the matrix of the major liquid phase of Fe 75 Cu 25 and Fe 25 Cu 75 particle samples, and the two or three layer structure of Fe 50 Cu 50 particle samples. In particular, all the samples exhibited a phase separation caused by the metastable miscibility gap and the dendrite growth of Fe phase with the decrease of the cooling rate.","PeriodicalId":17337,"journal":{"name":"Journal of The Japan Institute of Metals","volume":"65 1","pages":"251-256"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81618404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In solutions containing three kinds of additives such as gelatin, thiourea and chloride ions, the surface roughness of deposited Cu decreased with increasing the concentration of thiouea and gelatin and decreasing the chloride ions. On the other hand, the throwing power of deposited Cu was improved with decrease in thiourea and increase in gelatin in solutions containing three kinds of additives. The throwing power of deposited Cu was significantly improved in solution containing both gelatin and chloride ions. The polarization resistance dE/di for Cu deposition increased in solution containing both gelatin and chloride ions, which resulting in improvement of throwing power of Cu deposition. As small amounts of thiourea have a depolarization effect on Cu deposition, a leveling effect is expected owing to the promotion of deposition at recesses.
