Overview:

We are seeking improvements in the mechanical properties of Aluminum that can lead to reductions in weight, reductions in cost or increased formability.

Background:

Weight reduction is critical for OEMs during part manufacture in order to meet emissions targets. There are many constraints in casting and sheet material processing – Elongation, yield, UTS, density, and Young’s modulus. Any methods to improve one, some, or all of these would open up designs for further mass loss, cost reduction, and/or formability.

 Constraints:

  • No increase in weight, cost or formability
  • Mechanical performance better than current materials
  • Density decrease 10%-20% , while maintaining mechanical properties– ys, uts, elongation, Young’s Mod.
  • Young’s Modulus increase 50-100% , while maintaining mechanical properties – ys, uts, elongation, density
  • Density decrease 10%-20% and Modulus increase 50-100% , while maintaining mechanical properties – ys, uts, Elongation.

 Possible solution areas:

  • Castings – Alloy development and alloy elements
  • Computational and design approaches

Desired outcome of the solution:

Simple modification of metals that leads to significant mechanical performance.

Field of use and intended applications:

Part manufacture

Previously attempted solutions:

Novel alloys for sheet or extrusion mills
