2018 TMS Annual Meeting & Exhibition: Environmentally Assisted Cracking: Theory and Practice: Organized by Bai Cui; Raul Rebak; Sebastien Dryepondt; Srujan Rokkam

Environmentally assisted cracking (EAC) has become a significant limit for the lifetime of structural material components in harsh environments in many fields, such as the oil and natural gas industry, advanced nuclear power plants, and navy applications. The purpose of this symposium is to provide an international forum to foster the discussion of the critical problems in EAC and recent advances in both experiments and modelling. This symposium seeks technical presentations related to experimental and/or modeling studies of various types of EAC, such as hydrogen embrittlement, stress corrosion cracking, corrosion fatigue, and liquid metal embrittlement. The symposium will encompass, but not limited to, the following themes: - Models to understand EAC mechanisms and predict the lifetime of structural materials in harsh environments; - Experimental methods for the performance test of EAC in the laboratory and real environments; - Development of physics-based approaches or multiscale models for EAC monitoring and prognostics; - Fracture and fatigue of alloys in hydrogen environment; - Stress corrosion cracking of alloys in high-temperature water, seawater, or other environment; - Degradation of materials in liquid metal environment; - EAC in additively manufactured parts; - EAC in high-entropy alloys.

2015 TMS Annual Meeting & Exhibition: Nano- and Micro-Mechanical Measurements in Harsh Environments: Organized by Peter Hosemann; Jeffrey Wheeler; Verena Maier; Douglas Stauffer

Most materials are exposed to an environment different than that found in laboratory conditions, and it has been recognized that a material’s properties change based on the environment to which it is exposed. Therefore, understanding the mechanisms by which a material’s properties change in harsh environments (e.g. high and low temperatures, radiation, high strain rate deformation, and corrosive agents) is key to understanding materials behavior in service conditions. Nano- and Micro-scale material testing has been utilized to understand the basic phenomena of materials degradation and behavior. An obvious next step is to expand these valuable measurements to the environments that materials are exposed to during service conditions in order to study the synergistic effects between harsh environments and materials property degradation on the nano scale. The harsh environments materials experience can have a direct impact on the performance of nano-devices and nano-enabled energy systems for power, defense, and civil applications. For these reasons, we assert that we need to incorporate the environmental nano- and micro-mechanical measurement of materials, and we propose this symposium to accomplish this end. We are welcoming abstracts on materials evaluated using nano- and micro-mechanical measurements at low or high temperatures, chemical environments (gas, aqueous), radiation or any other harsh environment.

2015 TMS Annual Meeting & Exhibition: Structural Materials, Heat Transport Fluids, and Novel System Designs for High Power and Process Heat Generation: Organized by Peter Hosemann; Peiwen Li; Kumar Sridharan; Bruce Pint

High temperature sources are desirable for a wide range of engineering and industrial applications. Many renewable energy systems have the potential to develop a heat source for desirable high temperatures. Especially with the development of new Nuclear Power (NP), Clean Coal (CC) concepts as well as Concentrating Solar Power (CSP) concepts with high temperatures for process heat, hydrogen generation or efficient energy storage become viable options. The push to higher temperatures (>750oC) increases the need for different heat transport fluids and raises the question of the limits of structural materials available and deployed today. Harsh environments (temperature, corrosion, stress from flow of heat transport fluids, time, cost, pressure and cyclic loading) make this application challenging for the materials deployed and the limit of what conventional materials may be exceeded. In this symposium, we are providing a platform for a thorough discussion of all materials aspects associated with high temperature heat transport systems especially deployed in CSP,NP and CC systems with a particular focus on the structural materials. We are inviting application oriented papers as well as fundamental scientific contributions associated with interaction of structural materials with novel heat transport fluids (liquid salt, liquid metal, hydrocarbon, supercritical steam, supercritical CO2, etc.) including new heat transfer design concepts . Mechanical strength, high temperature durability as well as corrosion resistance of structural materials in any of the environments listed are of interest. 1) Expected session topics include: Materials for very high temperature heat transport systems with novel heat transport media, including but not limited to liquid metal, salt, sand, supercritical CO2. 2) Materials in high temperature, high pressure water systems 3) High temperature properties of the structural materials, including thermal cycling 4) Fundamental aspects of chemistry control to prevent corrosion in these systems. 5) Materials needs for new heat transfer designs It is the intention to focus on the specific issues associated with this application with solid material science background and to explore potentially unusual solutions and approaches. This symposium intends to bring together applied materials engineers as well as basic material scientists.
