The microstructure evolution of electroplated copper films was characterized by electron backscatter diffraction (EBSD). Special care was taken during the preparation of the cross-sectional specimens and microstructure analysis to obtain reliable results. The film exhibited a columnar grain structure with a large fraction of twin boundaries. Annealing induced normal grain growth and caused many...

Sample of CsAg2I3 was prepared by solid state reaction. Then, microstructure parameters of this sample have been determined using wide angle X-ray scattering WAXS method. As well as, Cell parameters of crystal structure have been refined using CHEKCELL program. This analysis states that the lattice intrinsic strainof the sample is so small and the crystal size is on the order of 559Å. Keywords—...

This article gives a brief description of the use of diffraction contrast transmission electron microscopy for characterizing the deformation microstructure. The capabilities and limitations of different modes of microscopy are also discussed. One of strengths of transmission electron microscopy technique is its capability to identify uncommon deformation system. This is illustrated by the anal...

Microstructure freeform surface is a type of freeform surfaces which is widely used in optical-mechanical-electronic components with increasing high precision requirement. This paper presents the characterization of structured freeform surfaces based on a pattern matching analysis method. The method employed rough matching by micro-structure features and then precise matching based on least squ...

in this research, graphitization transformation of a commercial hypereutectoid steel called ck100 was studied by the dilatometric experiments at the range of 600 – 700 °c from prior martensitic structure. also the effect of quenching media on the initial graphitization time and completion of transformation has been discussed. also, graphitization transition from the different prior microstructu...

A comparing study on formation and microstructure features of aluminum titanate is investigated through both solid-state and sol-gel processes. Aluminum titanate formed by firing at 1350ºC and 1450ºC for 4h in solid-state process. In the sol-gel process formation of submicron sized particles is followed by addition of sucrose into the transparent sol. XRD analysis was confirmed the formation of...
