1. Forging Aluminum for Aerospace Pressure Vessels
By: Cindy, Ryan, Diego, Aidan, Laura, Elizabeth
Mentor: Andrew Cantrell
“We have empowered our core values by taking a new spin on scaleable synergistic metallurgic management methodology. Our robust vertical solution will leverage impact across a wide spectrum of design industries and take advantage of this window of opportunity to strengthen our body of work at a cut and dry price.”

2. Jorgensen Forge
Manufactures high-quality forgings from material grades
Low alloy steels
Aluminum alloys
Titanium alloys
Nickel base alloys.
Customers include: US Navy, United Launch Alliance (ULA), and SpaceX

4. Our Project
Determine which alloy of aluminum would be best for use in a rocket
Why use Aluminum?
Stain/Work Hardening
Precipitation Hardening
Grain Refinement
Aluminum because it is strong and light
Stain/work hardening:stretching past yeild point then stopping
Grain refinement:aligning and reducing size of grains to make smaller. done by heating and cooling at different rates
Precipitation hardening (Age Hardening): heating it up to draw out impurities in the solute that impede crystal lattice movement, making it stronger

5. Determining an Alloy for Rocket
Conductivity
Hardness
It is important to be able to distinguish between alloys after their creation in order to assure the quality of the alloys.
The two major traits tested are hardness and conductivity.
Hardness is measured by applying a measured load to the surface of the alloy and measuring the displacement created.
Conductivity is tested with a current applied to the surface of the alloy.
Various alloys can be determined by their own particular conductivity and hardness.

6. Aluminum Alloys 1000 series is pure aluminium
2000 series is alloyed with copper
3000 series is alloyed with manganese
4000 series is alloyed with silicon
5000 series is alloyed with magnesium
6000 series is alloyed with magnesium and silicon
7000 series is alloyed with zinc
8000 series covers any other mixture not covered by the previous series
