Scope Additive manufacturing offers a new paradigm in part design for complex architectures however the availability of additive capable existing or new materials is minimal. The need for materials and alloys designed specifically for additive technology is increasing rapidly, particularly in extreme environments. Successful operating in extreme environments requires carefully selected materials and component designs. Conventional alloys are designed based on constraints of conventional materials processing and manufacturing technologies such as casting, forging and hot rolling or sheet metal forming. The unique solidification conditions during these processes have made expanding current conventional alloys to Additive Manufacturing difficult and made the introduction of new designed materials a technology challenge. What is more, the intrinsic properties of AM (i.e., rapid solidification, melt pool dynamic, cyclic heat treatment) can be exploited to design novel materials. Integrating materials, design, and manufacturing innovation is a new frontier that requires critical attention to harness the full potential of AM technology.
The goal of this symposium is to highlight research in novel alloys and application driven material design with a focus on how a fundamental understanding of the thermodynamic and kinetic boundary conditions, as well as using ICME approaches, machine learning, and artificial intelligence enable introducing new alloy systems for additive manufacturing. The technical challenges to be addressed in materials design for additive manufacturing for super materials and extreme environments includes but not limited to secondary deleterious phase formation, porosity and vaporization, melt-pool stability, etc. Technical sessions will emphasize the following categories:
Super/Hypersonic Environments
Super Materials
Ultra-High Temperature (>1400C)
Extreme Oxidative or Corrosive Atmospheres
High Flux Operation
Extreme Temperature Swings (>500C delta) (e.g. orbital and space applications)
Ultra Low Temperature (e.g. Liquid Helium or Hydrogen)
Elevated Temperature Light Alloys (Aluminum & Magnesium)
Materials-Design Integration for Superior Performance (e.g. Heat Exchangers, Meta Materials, Auxetic Materials)
Both experimental and modelling submissions are encouraged, especially in which modelling, or theory is applied and validated experimentally. Materials systems of interests are including but not limited to structural materials, different types of Steels, Aluminum, Titanium, Copper, Refractory Alloys, High Entropy alloys, and Bulk Metallic Glasses. Functional materials will also be considered.
