Competitiveness of the economies of border regions

The article is dedicated to the problem of competitiveness of border regions as subjects of the Russian Federation having specific characteristics. The authors focus on the stages, during which border regions build their competitiveness, as well as analyse certain indices characterizing it. They examine the role of these regions in the development of international trade and economic relations, cross-border cooperation and international integration, taking the North-west federal district and the Republic of Karelia as a case-study. The article describes the mechanisms of building and increasing competitiveness of border regions in today’s Russia both in general and, particularly, in the Republic of Karelia as a border region of the North-west federal district

DETERMINATION OF THE CRITICAL POINTS OF THE AMORPHOUS ALLOY SYSTEM Fe–Si–Nb–Cu–Mo–B

Методами калориметрии, дилатометрии и терморентгеновского фазового анализа определили температурные интервалы фазовых и структурных превращений в исходно аморфном сплаве системы Fe–Si–Nb– Cu–Mo–B, полученном спиннингованием. Для скоростей нагрева 0,3…0,5 o/сек установлен температурный интервал существования данного сплава в нанокристаллическом состоянии.The samples of amorphous ribbon of Fe–Si–Nb–Cu–Mo–B alloy system were studied using methods of calorimetry, dilatometry and thermo-X-ray phase analysis. The alloy was heat treated. Data about thermal effects, changes in geometric dimensions, changes in the phase composition, and about critical points are obtained. Interval of nanocrystallic state existence for heating rate 0.3…0.5 o/sec was determined

THE CRYSTALLOGRAPHIC TEXTURE SIMULATION OF TMCP

The TMCP crystallographic texture has been simulated. This texture arises as a result of hot austenite rolling and subsequent transformation into conformity with the ORs of Kurdjumov-Sachs. From the possible orientations of ferrite, the orientations arising on the austenite boundaries of CSL Σ3 were.Работа выполнена при финансовой поддержке стипендии Президента Российской Федерации (проект СП-3775.2021.1)

Amorphous Magnetic Alloy Based on the Iron-Silicon System

Изобретение относится к металлургии, а именно к аморфному сплаву на основе системы железо-кремний-магний, который может быть использован в качестве материала для магнитопроводов трансформаторов, индукторов, дросселей и электродвигателей.
