Investigation of Nanocrystalline Materials by Perturbed Angular Correlation and Supplementing Experimental Techniques
The properties of nanocrystalline materials are essentially determined by the grain size and the properties of the grain boundaries of the respective material. Using PAC for the investigation of nanocrystalline materials new information about structural properties and, in case of nanocrystalline semiconductors, electronic properties are obtained. In combination with “classical” experimental tec...
متن کاملPhase Transitions in Oxides Studied by Perturbed Angular Correlation Spectroscopy
Radioactive atoms located on cation sites in oxide matrices can be used to monitor phase transitions by measuring the electric or magnetic hyperfine interactions by means of Perturbed Angular Correlations spectroscopy. The article illustrates three types of phase transitions studied with 'in tracers and their daughter nuclei m C d , namely magnetic, structural and REDOX phase transitions in bin...

Experimental Investigation of Thermal Conductivity of Aluminum Alloy 3003 Produced by Equal Channel Angular Rolling Process
Equal channel angular rolling (ECAR) process is one of the methods that have been used to make ultra-fine materials by imposing severe plastic deformation. After repeating the process several times, a large effective strain is applied to the sample that can cause decreasing the grain size and improving the mechanical and physical properties of the metal. In this study, thermal conductivity of t...
