Metals CMRG

Metals CMRG

Consortium Lead: Prof. Timothy P. Weihs (JHU)

ARL Lead:
Dr. Tomoko Sano

Model Material: Magnesium

The magnesium alloy system is the model material for the Metals CMRG because it is the lightest-weight structural metal that offers the potential of approaching steel-like ballistic performance while using conventional low-cost and time-tested processing techniques. We are enhancing the dynamic performance of this hexagonally-close-packed metal using experimentally validated modeling and alloy design to control dynamic strengthening and failure mechanisms, including deformation twinning.

Application: The U.S. Army’s Stryker vehicle incorporates magnesium in its structure. In comparison to steel, magnesium offers the potential for a lightweight metal system that could enhance the deployability and protection of military vehicles.

Current Consortium Research Groups
  • Dynamic Deformation and Strength (El-Awady, Falk, and Ramesh, JHU; Bhattacharya and Ortiz, Caltech; Kimberley, NMT; Joshi, Univ. of Houston)
  • Thermal Mechanical Processing (Weihs, JHU; Bhattacharya and Kochmann, Caltech; Sankar, Xu, and Yarmolenko NC A&T; Wei, UNCC)
  • Void Dominated Failure and Spall (Hufnagel, JHU; Ortiz and Bhattacharya, Caltech; Wilkerson, Texas A&M)
