Abstract Continuous Equal Channel Angular Pressing (C-ECAP) is a High Shear Deformation (HSD) processing method that has been shown to improve the mechanical properties of many alloys. While laboratory-scale ECAP machines have successfully produced microstructures that enhance strength and other properties, their slow processing rate is a barrier to their widespread adoption by the metals production industry. To determine the viability of high-speed HSD production of a commercial alloy, 316 LVM stainless steel was subject to C-ECAP at speeds up to 42.5 mm/second to produce billets with repeatable tensile strengths exceeding 1000 MPa. The high-rate shear induced intersecting shear bands but they did not develop into shear cracks.
