Data Intensive Imaging for 3D Atom Probe
Atom Probe Tomography (APT) combines atomic imaging with a time-of-flight mass spectrometer to provide direct space three-dimensional, atomic-scale resolution images of materials with the chemical identities of all the detected atoms. Quantitative analysis of APT data through advanced data mining methods enhances the chemical characterization of alloy systems and accounts for the statistical un...
متن کاملMultivariate statistical analysis of atom probe tomography data.
The application of spectrum imaging multivariate statistical analysis methods, specifically principal component analysis (PCA), to atom probe tomography (APT) data has been investigated. The mathematical method of analysis is described and the results for two example datasets are analyzed and presented. The first dataset is from the analysis of a PM 2000 Fe-Cr-Al-Ti steel containing two differe...
متن کاملOn the Statistical Analysis of Atom Probe Data
The statistical techniques that have been applied for presenting and analyzing atom probe data are critiqued. These techniques include raw data analysis, character plots, ladder diagrams, frequency distributions of composition profiles, Markov chains, contingency tables, cross correlations, power spectrum, and autocorrelations. A comparison of the suitability of the individual techniques for sp...
متن کاملMultivariate Statistical Analysis of Atom Probe Tomography Data
Multivariate statistical analysis (MVSA) methods have been shown to yield many advantages in analytical instrumentation techniques because they offer an objective means to find complex information correlations in data that are not obvious to an observer and they maximize the discrimination of low-level signals from noise. Because they are objective in nature, the methods hold promise for automa...
متن کاملAtom-probe Analysis of Zircaloy
Zirconium based alloys in the Zircaloy series have been analysed with atom-probe field-ion microscopy. During specimen preparation an anodic layer is formed, containing about 50% oxygen. In preliminary analyses of the matrix al1 the minor elements Fe, Ni, Cr and O were detected, and it appears possible to determine with the atom-probe whether any particular heat treatment causes matrix depletio...
