Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed FeCr(Si)N Stainless Steel
Advanced Engineering Materials, Volume 27, Issue 14, July 2025.The alloying element Nitrogen enhances stainless steel strength, corrosion resistance, and stabilizes austenite. This study develops austenitic FeCr(Si)N steel production via powder metallurgy. Fe20Cr and Si3N4 are hot isostatically pressed, creating an austenitic microstructure.

Open innovation under authoritarianism: The case of the Soviet Union
The Journal of World Intellectual Property, Volume 28, Issue 1, Page 3-23, March 2025.Abstract The Soviet Union was a productive and technologically developed economy. It achieved a remarkable transformation from a feudalistic society to an advanced industrial society. How was it able to do this? This article argues that such rapid industrialisation was possible because the Soviets invested in legal institutions that created a special ...

steel research international, Volume 95, Issue 11, November 2024.The study combines a thermodynamic equation with a kinetic model to predict nitrogen content (0.150–0.400%) at the end of argon oxygen decarburization process when producing nitrogen‐alloyed stainless steels. The adjustment of nitrogen content is achieved by blowing nitrogen–argon mixtures through blowing, and the model successfully predicts this ...
