Advancing new materials for manufacturing

Robots on manufacturing floor

Materials scientists won a TechConnect Defense Innovation Award for research exploring the processing of third-generation aluminum-lithium alloys for use in advanced manufacturing. John Lewandowski, the Arthur P. Armington Professor of Engineering II in the Department of Materials Science and Engineering, led Case Western Reserve’s efforts on the project, in collaboration with other universities, industrial members and government labs with the support of Lightweight Innovations for Tomorrow (LIFT), a public-private partnership dedicated to advancing new lightweight materials manufacturing technologies.

The team, led by United Technologies Research Center and LIFT, has developed and validated a visco-plastic model to predict local microstructure development during the forging of third-generation aluminum-lithium alloys.

Lewandowski has also received six new awards totaling more than $2.0 million in funding for research in advanced manufacturing. New projects include:

  • $450,000 from America Makes – “Accelerating MAMLS (Maturation of Advanced Manufacturing for Low-Cost Sustainment) Direct Part Production: Effects of Defects in Laster Powder Bed Fusion”
  • $426,500 from the Office of Naval Research – “Process-Structure-Property Study on CP-Ti Produced Via High-Deposition AM Laser-Hot Wire”
  • $450,000 from the Office of Naval Research – “Investigating the Mechanical Behavior of 5XXX Aluminum Alloy Structures on the HMCS Iroquois/Athabaskan”
  • $100,000 from the Office of Naval Research and U.S. Naval Air Systems Command – “Microstructure Informatics for Propagating Uncertainty in Material and Processing to Performance Predictions of AM Titanium Parts”
  • $495,000 from the Office of Naval Research – “Sensitization Temperature/Time Dependence of Environmental Cracking in Al-5456-H116 and Al-5083-H116 and Novel Laser Remediation Treatments”
  • $157,200 from Lightweight Innovations for Tomorrow – “Friction Stir Welding of Dissimilar, Bi-Metallic and MMC Components (Co-PI with Associate Professor Matthew Willard-PI)
