新工科背景下ODS钢增材制造与热处理教改探索

An Exploratory Study on the Teaching Reform of Additive Manufacturing and Heat Treatment of ODS Steel under the Emerging Engineering Education Initiative

  • 摘要: 随着“新工科”建设的深入推进,金属热加工课程面临从传统“成形”向“控性”转变的迫切需求。氧化物弥散强化(ODS)钢作为第四代核能系统的候选材料,其增材制造与热处理工艺代表了材料基因工程与智能制造的交叉前沿。本文针对当前热加工教学中存在的“工艺与材料脱节”、“前沿技术滞后”及“实验手段单一”等问题,提出构建“增材制造ODS钢全流程教学设计”的改革方案。通过引入“粉末设计-激光成形-组织表征-热处理调控”的项目制教学模式,将微观组织演化与宏观性能控制的科学逻辑贯穿始终。实践表明,该教改方案能显著提升学生解决复杂工程问题的能力,为高端装备制造领域培养具备跨学科思维的卓越工程师提供支撑。

     

    Abstract: With the deepening of the Emerging Engineering Education initiative, the course of metal hot working is facing an urgent demand for shifting its focus from traditional "shape forming" to "property control." Oxide dispersion strengthened (ODS) steel, as a candidate material for Generation IV nuclear energy systems, represents the interdisciplinary frontier of materials genetic engineering and intelligent manufacturing through its additive manufacturing and heat treatment processes. To address the existing problems in current hot working instruction—such as the disconnection between process and material, the lag in introducing cutting-edge technologies, and the monotony of experimental methods—this paper proposes a teaching reform scheme of constructing a "full-process instructional design for additively manufactured ODS steel." By introducing a project-based teaching model featuring "powder design-laser forming—microstructural characterization—heat treatment control," the scientific logic linking microstructural evolution and macroscopic property regulation is consistently emphasized throughout the course. Practice shows that this reform scheme can significantly enhance students' ability to solve complex engineering problems, providing support for cultivating outstanding engineers with interdisciplinary thinking for the high-end equipment manufacturing sector.
