钢铁材料是不断发展的新材料,这获益于持续不断的基础研究。钢铁研究总院结构材料研究所是国内外在钢铁材料研发领域最完全的研发机构,它重视钢铁材料的基础研究工作。评述了近年来钢铁材料基础研究的发展,包括提高钢材强度的基础研究、改善钢材寿命的基础研究和提高钢制部件服役安全性的基础研究等。通过这些基础研究,形成了创新性的微合金化技术、变形诱导相变理论、晶粒细化技术、在线软化退火技术、耐延迟断裂技术、抗疲劳破坏技术、氮合金化奥氏体钢技术、高韧性超高强度钢技术、热成形马氏体钢技术、核电用钢技术等。基础研究将会促进新一代钢铁材料的不断涌现。
Steel is a continuous development of new materials, which benefit from continuous basic research. Steel Research Institute Institute of structural materials is the most complete research and development institutions in the field of steel materials research at home and abroad, it attaches great importance to the basic research of steel materials. The development of basic research on steel materials in recent years is reviewed, including basic research on improving the strength of steel, basic research on improving the life of steel and basic research on improving service safety of steel parts. Through these basic researches, innovative microalloying technology, deformation induced phase change theory, grain refinement technology, online softening annealing technology, delayed fracture resistance technology, anti-fatigue failure technology, nitrogen-alloyed austenitic steel technology , High tenacity high strength steel technology, thermoformed martensitic steel technology, nuclear power steel technology. Basic research will promote a new generation of steel materials continue to emerge.
