Technical Description
The invention provides a highly cost-effective high strain rate plastic deformation method and an aero-ballistic device to manufacture reliable bulk metallic Functionally Graded Materials (FGMs). By firing structural alloy projectiles at ultra-high velocities against a stationary target plate, the system induces localized dynamic recrystallization to form a continuous, seamless property gradient in a fraction of a second.
Problems Addressed
- Inter-laminar Shear Stress Failures
- Severe Geometric Production Limits
- Expensive Additive Manufacturing Costs
- Interface Discontinuity and Layer Snapping
- Unreliable Component Lifespan Estimations
Tech Features
- Three-Tube Aero-Ballistic Gun Setup
- Pressure-Controlled Velocity Impact Range (100–750 m/s)
- Adjustable Oblique Target Tilted Alignment
- Ultra-High-Molecular-Weight Polyethylene (UHMWPE) Target
- Solid Aluminum Alloy Projectiles
- Sub-Grain Fracture Refinement (70 µm down to 10 µm)
- Hardness Increment (+45% to +52% increases)
Target Audience
- Defense & Armor Designers
- Advanced Materials Engineers
- Aerospace Propulsion Manufacturers
