1A review of in-situ EBSD experiments显示文摘Automated EBSD or Orientation Imaging Microscopy (OIM) systems are being used in combination with other equipment within the scanning electron microscope (SEM) to perform in-situ measurements. This paper briefly reviews OIM studies of in-situ experiments performed using tensile and heating stages as well as in-situ serial sectioning. In particular, in-situ OIM scan results on an aluminum alloy sample deformed in tension; phase transformations in a cobalt sample, recrystallization and grain growth in a copper sample and serial sectioning of a nickel super-alloy sample are reviewed.Stuart I.

2Crystalline phase of Y_2O_3 :Eu particles generated in a substrate-free flame process显示文摘In this study, factors affecting the crystal structure of flame-synthesized Y 2 O 3 :Eu particles were inves- tigated, especially the particle size effect and its interaction with Eu doping concentration. Polydisperse Y 2 O 3 :Eu (size range 200 nm to 3 m) powder samples with Eu doping concentrations from 2.5 mol% to 25 mol% were generated in either H 2 /air or H 2 /O 2 substrate-free flames. The crystal structure of the powder samples was determined by powder X-ray diffraction (XRD), which was complemented by pho- toluminescence (PL) measurements. Single particle crystal structure was determined by single particle selected area electron diffraction (SAED), and for the first time, by electron backscatter diffraction (EBSD). H 2 /air flames resulted in cubic phase Y 2 O 3 :Eu particles with hollow morphology and irregular shapes. Particles from H 2 /O 2 flames had dense and spherical morphology; samples with lower Eu doping concen- trations had mixed cubic/monoclinic phases; samples with the highest Eu doping concentrations were phase-pure monoclinic. For samples generated from H 2 /O 2 flames, a particle size effect and its interaction with Eu doping concentration were found: particles smaller than a critical diameter had the monoclinic phase, and this critical diameter increased with increasing Eu doping concentration. These findings sug- gest that the formation of monoclinic Y 2 O 3 :Eu is inevitable when extremely hot substrate-free flames are used, because typical flame-synthesized Y 2 O 3 :Eu particle sizes are well below the critical diameter. However, it may be possible to generate particles with dense, spherical morphology and the desired cubic structure by using a moderately high flame temperature that enables fast sintering without melting the particles.Bing Guoa Hoon Yim Wonjoong Hwang Matt Nowell Zhiping Luo 2011Particuology2011,9,1:4
