Scope Phase transformation is still one of the most effective and efficient means to produce desired microstructures in materials for various applications. This symposium is the third in a series of annual TMS symposia focusing on phase transformations and microstructural evolution in materials during processing and in service. It intends to bring together theoretical, experimental and computational experts to assess the current status of theories of phase transformations and microstructure evolution in solid states. In addition to fundamental understanding of the mechanisms underlying phase transformations and microstructure evolution, attention will also be given to the utilization of unique transformation pathways to develop novel microstructures for advanced structural and functional materials.

The topics of choice for this year include, but are not limited to:
-New insights into solid-solid phase transformations by coupling atom probe tomography (APT) with other experimental and computational tools. APT is a powerful technique for quantifying atomic scale, local element concentrations at interfaces in thin surface and multilayered films and a wide range of metallic, semiconducting, and hybrid/composite materials. APT, when coupled with information obtained by other powerful characterization techniques such as electron microscopy and spectroscopy, has lead to novel insights into the fundamental mechanisms associated with solid-solid phase transformations. While some mechanistic insights have been discussed and recorded in seminal peer-reviewed publications, previously available experimental tools did not usually afford the ability to discern these mechanisms at the atomistic scale. The motivation is to bring together multiple groups of researchers coupling atom probe tomography with other experimental and computational tools to discuss exciting advancements in understanding solid-solid phase transformation mechanisms.

-Iron-chromium alloys are the basis for stainless steels, making their characterization essential for understanding the evolution of stainless steels. The study of iron-chromium based alloy microstructures and their influence on properties (in particular, mechanical and corrosion resistance) has been an active field for nearly a century, but modern experimental and numerical techniques (and their combinations) have recently brought important new insights into this field. This session aims to bring together scientists studying iron-chromium alloys with experimental (APT; Mössbauer spectroscopy; Small Angle Neutron Scattering....) and/or a modeling (classical thermodynamics; Ab-Initio, Molecular Dynamics, Monte Carlo & Phase Field modeling) approaches. The fundamental understanding of pair interaction functions, nucleation and growth versus spinodal decomposition, and segregation to grain boundaries, for example, and consequences on properties (e.g. mechanical behavior, radiation sensitivity, and corrosion resistance) are of interest. Investigations that utilize both experimental and modeling approaches are highly encouraged.
