Study on nitrogen pores, microstructure, and mechanical properties of nickel-free high-nitrogen stainless steel fabricated via LDED regulated by heat input

The most significant challenges in the laser additive manufacturing of high-nitrogen steel are nitrogen loss and nitrogen pores, which significantly impact the microstructure and mechanical properties of the fabricated parts. In this paper, the regulation mechanisms of nitrogen loss, nitrogen pores,...
