Modification of Nitrogen-Containing High-Chromium Steels by Nanosized Lanthanum Hexaboride

Abstract:

The paper presents the results of a study of the lanthanum hexaboride nanosized powder modification effect on the cast structure of martensitic and austenitic steels deoxidized with aluminum and silicon. The study was conducted on high-chromium steels of austenitic and martensitic classes, and nanosized lanthanum hexaboride powder was used as a modifier. Studies of the chemical composition of the obtained samples, qualitative and quantitative analysis of non-metallic inclusions, the structure of the steel and thermodynamic modeling were carried out.
