Note:

1.1.1 (SAM); This project will investigate and evaluate novel high entropy alloys (HEAs), complex concentrated alloys (CCAs), and shape memory alloys (SMAs) as die coating materials using direct metal deposition additive manufacturing techniques for forging die repair. HEA, CCA, and SMA materials have higher corrosion resistance mechanical properties compared to traditional die materials. SMAs are a separate class of materials that exhibit a large increase in ductility due to a phase transformation upon heating or loading. Applying a thin layer of these laser-coated alloys to the die cavity has significant implications for the forging industry. Extending die life decreases the need for processing new dies to replace worn or damaged dies. An extended lifetime also reduces the overall cost of repairs/maintenance of dies and increases press uptime and production through the time saved that would normally be spent replacing or repairing worn or damaged dies. The use of novel materials such as HEA, CCAs, and SMAs for laser-coating of forging dies has recently been shown to nearly double the lifetime of repaired dies. This project will leverage the results of the Forging Industry Education Research Foundation (FIERF) project to potentially double current die lifetimes, reducing costs and lead times for both the forging industry and DOD. This project aims to take an information theoretic view on the investigation of the fundamental limits of cryptographic primitives. Most existing literature in theoretical computer science community considers the complexity theoretic formulation that focuses on performance metrics along different scaling laws when compared to our Shannon theoretic formulation that concentrates on the landmark information theory concept - capacity. This viewpoint has been successfully applied by the PI to unravel insights on the fundamental capacity limits of several canonical cryptography problems such as broadcast encryption, conditional disclosure of secrets, and secure multiparty computation. Alongside, inspired by recent advances in network information and coding theory, a set of sophisticated mathematical tools have been developed over the past several years and are expected to play instrumental roles in the proposed study, including but not limited to: interference alignment based code design, generic subspace codes, linear dimension counting, information inequalities framework for converse derivation, and random binning and algebraic codes. The PI, as a key contributor of these techniques, will apply and further develop them in the context of the proposed study.
