Solute-solute interactions in intermetallic compounds studied using perturbed angular correlation of gamma rays
(2017-05)Interactions between pairs of solute atoms dissolved in a binary intermetallic compound were studied. Perturbed angular correlation of gamma rays (PAC) was used to detect solute atoms next to impurity PAC probe atoms in ... -
Extending Miedema's Semi-Empirical Model to Predict Defect Site Preferences and Formation Enthalpies of Ordered Compounds
(2016-12)Miedema's Semi-Empirical Model is a method in which a simple calculation provides a rough estimate of the formation enthalpy of a single defect atom (of element X) surrounded completely by a solvent element (element A). ... -
A qualitative look at the thermodynamics of ternary phase diagrams
(2016-05)In 2014, Collins’ research group embarked on experiments using Perturbed Angular Correlation (PAC) spectroscopy to measure interactions between solute atoms in ternary alloys. PAC requires a probe atom, 111In, making the ... -
Investigations of ternary alloys using perturbed angular correlations
(2015-06)The intended goal of this research was to investigate interactions between solute atoms in intermetallics using a nuclear probe method, Perturbed Angular Correlation (PAC) of gamma rays. The PAC probe, radioactive 111In, ...
