The investigation of the high energy rate extrusion process continued. The effect of ram mass and reduction ratio was analyzed on pull-off length with results that compare ell with experimental data. The Ti-6A L- V alloy was extreme in 10-ft lengths. Steel extrusions 10 ft long were extruded but they separated inertially into smaller lengths. A braking device was made which gives the desired effect but not to a degree sufficient for making 10-ft extrusions of steel. The extrusion constants for Ti, steel and Al under high-velocity extrusion conditions were determined. The speeds and stresses involved during the extrusion period were measured and analysis was made of the requirements for a successful braking device.
