Phase Transformations and Entropy of Non - Equilibrium Materials
The importance of vibrational entropy to solid-state phase transformations has become well established over the past decade. Considerable experimental and theoretical work has gone into investigating the vibrational entropy of phase transformations in metallic alloys. This thesis examines phase transitions in three unique systems, unified in the experimental tools used to probe the nature of th...
متن کاملThermal stability and phase transformations of martensitic Ti–Nb alloys
Aiming at understanding the governing microstructural phenomena during heat treatments of Ni-free Ti-based shape memory materials for biomedical applications, a series of Ti-Nb alloys with Nb concentrations up to 29 wt% was produced by cold-crucible casting, followed by homogenization treatment and water quenching. Despite the large amount of literature available concerning the thermal stabilit...
متن کاملNovel pressure-induced phase transformations in hydrous layered materials
[1] High-pressure Raman and X-ray diffraction data on single crystals of hydrous layer-structure minerals, dickite and gibbsite, reveal structural phase transitions occurring between 2.0 and 2.5 GPa. In the case of dickite, this is the first documented occurrence of a pressure-induced phase transformation in a 1:1 phyllosilicate. Above the transition the structure of individual 1:1 layers remai...
متن کاملPhase Stability and Phase Transformations in Plutonium and Plutonium-Gallium Alloys
The complexity of phase stability and transformations in plutonium alloys is reflected in the plutoniumgallium (Pu-Ga) phase diagram, which is perhaps the most complex of all binary systems. Although many investigations have explored phase equilibria, transformation systematics, and structure/property relations in the Pu-Ga system, many outstanding problems remain and new issues regularly appea...
