Shear Form Inc SBIR Phase II Award, April 2021

In Phase II, Shear Form, Inc will apply a severe plastic deformation (SPD) processing technology to Ultra-High Strength Steels (UHSS), specifically 4340M and AF 9628, to enable penetration improvement for warhead casings. Equal Channel Angular Extrusion (ECAE) will be used to SPD process the steels under ausforming conditions. Larger scale experiments will be trialed to determine suitability for scaling, and to derive knowledge for manufacturability. The knowledge gained form Phase I will facilitate microstructural engineering to toughen and strengthen steel casing materials considered for casing manufacturing. Successful application of this technology will improve bomb penetration performance at a low cost.
