Russian Engineering Research Aims and scope

Abstract

The influence of pulsed current on the additive manufacture of high-alloy 308LSi steel is investigated. Frequencies of 5000 Hz or more have the greatest influence on the structure and properties. In the absence of pulses, the mechanical properties of the printed product correspond to those of steel produced by standard technology, whereas current pulses increase the strength by 15–20%.
