Abstract:Faced with the challenges of high-end industrial development and diversified steel demand in the context of the new technology revolution, clarifying the development trend of steel materials and their technologies is of great significance for the deep coupling of the new technology revolution and the high-quality development of the steel industry.The research uses the LDA model to comprehensively explore the technological topics of steel materials and their development trends, and finally refine the development characteristics and future development of steel materials. It indicates that the research on steel materials are mostly focused on upstream-basic research.The performance of steel materials will focus on high performance,composite, low-dimensional, and intelligent.The types of materials tend to extend from structural materials to functional materials.It will start from the perspective of market, technology and resources, and enter a new era of intelligent design, intelligent production and intelligent service of steel materials in the future.
