Title: Probing the Early Stages of Second Phase Nucleation and Phase Separation in Titanium Alloys
Titanium alloys have been applied in a number of product areas, including commercial aircraft and engines and, in contrast, bio-medical engineering, largely because of a combination of attractive properties and because they are relatively light in weight. However, the full exploitation of Ti alloys requires manipulation of nano- and micro-structure to effect a range of combinations of properties, and this in turn requires a detailed understanding of the processes involved in the evolution of these nano- and micro-structures. Due to many unanswered questions regarding the structure of these important alloys right from the atomistic length scales to the more macroscopic length scales, it is necessary to focus effort on developing a more thorough understanding of these structures and their development, and this is a central objective of this program. The unique and state-of-the-art characterization capabilities available in CART at UNT, including the trio of the dual-beam focused ion beam, the high-resolution TEM, and, the 3D atom probe microscope, will allow for these detailed studies to be successfully conducted at unprecedented resolutions.
