This behavior has been considered as that the fi rst – and latter – half parts of the initial magnetization curve correspond to the magnetization reversals of multi – and single – domain grains, respectively. In this study, the detailed magnetic domain structure of a Nd – Fe – B hot – deformed magnet has been studied for the initial magnetization and demagnetization processes by using a soft X – ray magnetic circular dichroism ( XMCD ) microscopy. The observed magnetization reversal behavior for the initial magnetization process is quite di ff erent from that previously considered. The multi – domain states move from grains to grains through the gradual displacement of domain wall passing through many grains, and then the massive domain wall displacement takes place. The latter part of domain wall displacement is similar with that found in the demagnetization process near the coercivity. Moreover, we found that there are several strong pinning sites which are identical for both the initial magnetization and the demagnetization processes. ［ doi:10.2320 / jinstmet.J2021041 ］ ( )","PeriodicalId":17322,"journal":{"name":"Journal of the Japan Institute of Metals and Materials","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88413403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a previous study, a model has been proposed based on dislocation theory to describe the relationship between dss and physical properties. For pure metals, it has been reported that the variation of dss follows the model. For alloys, although the effect of the normalized stacking fault energy ΓSFE/Gb has been investigated, that of other physical properties such as σ has not been well considered. In this study, physical properties of the Ni–Fe alloys were controlled by changing Fe content, and effect of the physical properties on dss obtained by the High–pressure torsion (HPT) straining was investigated. dss of Ni–Fe alloys became finer with increasing Fe content. This study revealed that decrease in dss of Ni–Fe alloys follow the previous model, which suggested that not only ΓSFE/Gb but also normalized flow stress σ/G affects dss of Ni–Fe alloys. It is presumable that the decrease in ΓSFE/Gb suppresses the recovery of dislocations, and the decrease in inverse of σ/G enhances the introduction of dislocation, which leads to a finer dss in the Ni–Fe alloys.

Therefore, by joining thermoplastic resin, which has been widely used in recent years, to porous aluminum, it is possible to achieve both strength and weight reduction while providing shock absorption properties. In this study, bonding of porous aluminum and a polycarbonate plate was performed. The polycarbonate plate was pressed against the heated porous aluminum to bond them. From the tensile test of the bonded specimen, it was found that bonded specimen, which was bonded at 400 ℃ can achieve higher strength than that at 300 ℃ owing to the anchor e ff ect. The bonded specimen, which was bonded at 400 ℃ , exhibited fracture at the porous aluminum part, while the bonded specimen, which was bonded at 300 ℃ , exhibited fracture at the bonded surface.","PeriodicalId":17322,"journal":{"name":"Journal of the Japan Institute of Metals and Materials","volume":"129 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76730081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
