Organizational Implementation of ICME in the Laboratory: Charles Ward1; 1Materials and Manufacturing Directorate, Air Force Research Laboratory
The Air Force Research Laboratory undertook a holistic implementation of Integrated Computational Materials Engineering (ICME) in the research laboratory environment just over 10 years ago. Efforts began with the launch of two foundational engineering problems to pave a path for ICME in both structural and functional material systems. These were quickly followed by the development of tools, infrastructure, and policies to capture and curate materials research data while providing avenues for collaboration with external research partners. As the field of ICME matured, the opportunities presented by the application of artificial intelligence and machine learning to materials research led to the establishment of several workforce development and pipeline efforts to better equip current staff, while developing a talent pipeline for future employment. Additionally, these same advances have led to progress in demonstrating autonomous materials research systems that accelerate materials discovery and development. These efforts, lessons learned, and future direction will be highlighted.

MPMD ICME Industry Implementation Award Recipient - ICME for High Strength Metal Alloys: Current Status and Future Challenges
: Louis Hector1; Anil Sachdev1; 1General Motors Global Technical Center
As the automotive industry moves towards electrification, high strength metal alloys will be needed along with material models for CAE simulations. Some significant challenges remain since these models must accurately represent the non-linear microstructural response to the multiple deformation modes and rates encountered in both forming and component performance, and also account for fracture since necking instability may be less relevant. Of foremost importance are accurate computer models of microstructure and microstructural evolution during plastic flow to incipient fracture. The effects of temperature must also be addressed in forming and in situations where strain rates lead to significant component heating. Here, focus will be on the status of ICME for metal alloys with specific emphasis on multiphase high strength steels that deform via martensitic transformation, and what the authors believe are the greatest future benefits that ICME has to offer. Ongoing challenges ICME faces towards broader implementation will be discussed.

Experimentalists in Quarantine: Building ICME Infrastructure and Talent Pipelines: Victoria Miller1; 1University of Florida
The global pandemic impacted experimentalists everywhere and slowed the pace of research. However, it also provided an opportunity to shift human resources toward the development of ICME tools and training. As the pandemic recedes these new resources are being implemented, ultimately accelerating materials development. This talk will describe several case studies from the University of Florida on new ICME tools that were enabled by quarantine. These case studies will include work on mitigating liquid metal embrittlement, reducing twin-mediated cracking in Mg alloys, and minimizing microtexture during thermomechanical processing of Ti alloys. Training an ICME-literate future workforce will also be discussed.
