In the as-milled state, the alloy specimens consist of nanocrystalline α-(Fe,Co). The formation of hard magnetic Sm2Co17 or Sm2Fe17 phases within the surrounding (Fe,Co) matrix during continuous heating was followed by in- situ X-ray diffraction experiments performed at the HASYLAB/DESY synchrotron radiation facility in Hamburg, Germany. The hard magnetic Sm2Co17 nanocrystalline phase forms at temperatures near to 800°C. The temperature evolution of the grain-size distribution was obtained from the integral breadth double-Voigt analysis of the broadening of the (Fe,Co)- matrix X-ray diffraction lines. The kinetics of microstructure coarsening seems to be influ- enced by grain boundary pinning (drag) effects correlated with the formation of a two-phase microstructure.","PeriodicalId":23897,"journal":{"name":"Zeitschrift Fur Kristallographie","volume":"23 1","pages":"351-354"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82427934","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 ability of tailoring the dimensional regime of nanoparticle ensembles represents a landmark achievement in nanoscience. A key aspect is, however, the development of appropriate methods of data analyses of these complex objects. We present, here, a new method for interpreting powder diffraction data, based on the use of the Debye Function and suitable to treat data collected on virtually any nanocrystalline material. The method has been presently limited to single-domain particles. Applications of technological interest are also discussed.","PeriodicalId":23897,"journal":{"name":"Zeitschrift Fur Kristallographie","volume":"1 1","pages":"105-110"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76493778","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 this paper this investigation is focused on the model system made of aluminium-silicon mixture at eutectic composition and corundum. In particular, the structural and microstructural features are investigated by high-temperature resolved X-ray diffraction (HTXRD) and bidimensional micro X-Ray diffraction (XRD 2 ).
