During the process, graphite was well-dispersed in double distilled water as a lubricant and sodium dodecylsulfate (SDS), followed by shaking and milling under low energy. The exerted sheer force led to continuous delamination of graphene flakes. The microstructural investigation was performed by SEM. Also, the energy dispersive X-ray spectroscopy (EDS) analysis was performed to determine distinct levels of carbon in different fragments of graphite. The ultrathin multilayer structure of graphite was successfully obtained using the surfactant of SDS, which can lead to the production of molecularly thin sheets by mechanical peeling. Moreover, it was found that this synthesis method has advantages, including cost-effectiveness and ease in performance for producing a lot of graphene nanolayers.","PeriodicalId":300463,"journal":{"name":"Journal of Composites and Compounds","volume":"450 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114057533","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}

The obtained phases, microstructure, and magnetic properties of these alloys were studied by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), and vibration sample magnetometer (VSM). XRD results indicated that after suitable time of milling, Ni and Cu were homogeneously distributed in the Fe matrix and (bcc) α-(Fe(Ni-Cu)) solid solution was obtained. It was found that by increasing Cu content in the alloy, work hardening increased, and thus the size of grains decreased while the internal micro strain increased. Also, morphological observations indicated that the addition of Cu led to formation of finer particles. Also, VSM analysis showed that the addition of Cu into Fe-Ni alloys lowered Ms. On the other hand, the coercivity increased by increasing copper content up to 1.5 at. %.","PeriodicalId":300463,"journal":{"name":"Journal of Composites and Compounds","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127603294","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}

The aim of this study is to improve the mechanical properties of hydroxyapatite for biological uses. For this purpose the effect of magnesium fluoride (MgF2) addition with different weight percentages (0, 5, 7.5 and 10) on the mechanical properties of pure hydroxyapatite sintered at various temperatures (900, 1000 and 1100 °C) for 1 hour was investigated. XRD analysis was performed to study the decomposition of hydroxyapatite and the transformed phases. The density, Vickers microhardness and fracture toughness of the specimens were measured. The SEM analysis was performed to investigate the microstructure of samples. The results showed that the decomposition of hydroxyapatite to tri-calcium phosphate (TCP) decreased with increasing MgF2. Also, an increment in density and mechanical properties of the specimens were observed with increasing the amount of hydroxyapatite. The fracture toughness of sintered pure hydroxyapatite increased from 2.3 to 1.3 MPa.m1/2. The specimen containing 10 wt. % MgF2 sintered at 1100 ° C showed the best mechanical properties.","PeriodicalId":300463,"journal":{"name":"Journal of Composites and Compounds","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131416662","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}
