Secondary electron hyperspectral imaging: nanostructure and chemical analysis for the LV-SEM

ABSTRACT

Materials engineers have increasing control over nanoscale chemical composition and nanostructures. The latter can be easily analysed by the scanning electron microscope (SEM) yet nanoscale chemical analysis in the SEM poses challenges. Nevertheless, nanoscale chemical analysis capabilities have been developed in the LV-SEM by secondary electron hyperspectral imaging (SEHI). In this article, the insights that SEHI has provided into well characterised semiconductor, photovoltaic, polymer and hard carbon materials are reviewed. Instrument and experimental considerations for the obtainment of secondary electron hyper-spectra are discussed and recommendations for future analyses in the LV-SEM by SEHI are made.     

Space charge dynamics in electron beam-irradiated PMMA

In this study, space charge was introduced into polymethyl methacrylate (PMMA) samples by electron beam. The effect of the electron beam on the conductivity and the permittivity of the PMMA sample were investigated, and the breakdown mechanism of the samples during charge detrapping was also studied. The experimental results clearly show that not only space charge injection but also space charge detrapping can lead to the breakdown of the samples. The dynamics of injected charges in the radiated PMMA samples and the mechanism of the breakdown resulting from the rapid discharge are discussed.

Modelling of anisotropic elastic properties in alloy 718 built by electron beam melting

ABSTRACT

Owing to the inherent nature of the process, typically material produced via electron beam melting (EBM) has a columnar microstructure. As a result of that, the material will have anisotropic mechanical properties. In this work, anisotropic elastic properties of EBM built Alloy 718 samples at room temperature were investigated by using experiments and modelling work. Electron backscatter diffraction data from the sample microstructure was used to predict the Young’s modulus. The results showed that the model developed in the finite element software OOF2 was able to capture the anisotropy in the Young’s modulus. The samples showed transversely isotropic elastic properties having lowest Young’s modulus along build direction. In addition to that, complete transversely isotropic stiffness tensor of the sample was also calculated.
