摘要
综述了胀断加工技术对连杆材料的特殊要求及胀断连杆用材料的发展现状,探讨了非调质钢胀断连杆组织性能控制的原理与策略。最后提出了扩大非调质钢应用的建议,强调应加强基础研究,揭示非调质钢的材料特性,特别是组织性能定量关系;强化"产学研用"结合,采用控锻控冷技术实现非调质钢胀断连杆组织性能的精确柔性系统控制。
In this paper, the requirements of fracture splitting technology on materials, and development of materials for fracture splitting connecting rod are reviewed. Principles and strategies of microstructure and mechanical properties control are discussed. Finally, the suggestion of expanding the application of air-cooled forging steel is proposed. Furthermore, basic scientific research should be strengthened, and material properties of air-cooled forging steel, especially quantitative relationship between micro-structure and mechanical properties should be revealed. The microstructure and properties can be controlled accurately, flexibility and systematically by TMCP technology.
