HYDROGEN AS A NEW ALLOYING ELEMENT IN METALS

摘要

Hydrogen-metal interaction phenomena belong to the most exciting challenges of today's physical metallurgy and physics of solids due to the uncommon behavior of hydrogen in condensed media and to the need for understanding hydrogen's strong negative impact on properties of some high-strength steels and alloys. The paper cites and summarizes research data on fundamental thermodynamic characteristics of hydrogen in some metals that absorb it endothermally at elevated temperatures. This paper summarizes and analyzes available data that demonstrate positive effects of hydrogen on structure and properties of metals and alloys and are of principal scientific and applied interest. Methodological support features for metal-hydrogen system studies are addressed.
