ABSTRACT:
A technique for manufacturing a product involves receiving material, providing plastic deformation to the material to at least partially form the product, and applying electric current to the material while providing the plastic deformation to the material. The electric current is configured to reduce flow stresses within the material during plastic deformation. In some arrangements, the electric current is a series of high-density, short electric pulses which increases plasticity due to increasing the dislocation mobility of the deformed material. In some arrangements, the electric current provides an electric current density through the material of at least 1000 Amperes per square millimeter with each electric pulse lasting no longer than 0.01 seconds.
