| 摘 要： | 冷作强化非调质钢是非调质钢领域中的一个重要分支，它通过微合金化、控制轧制和控制冷却，使微合金化元素的碳氮化物弥散析出而产生沉淀强化和细晶强化，在此基础上再通过冷变形产生加工硬化，使钢的强度进一步提高，在不经过调质处理的情况下，即能达到所要求的性能指标。马钢通过成分优化设计、高速线材低温热机械轧制及组织控制技术，开发出具有原始创新性的8．8级MFT8冷作强化非调质冷镦钢，并通过冷拔和时效处理等关键生产工艺试验、安全性和环保性评价等应用技术研究，开发出了冷作强化非调质冷镦钢线材产品，并在紧固件行业得到了实际应用。

| Abstract: | Cold-work-strengthened non-quenched non-tempered cold-heading steel is a important branch of non-quenched non-tempered steel.Through microalloying,controlled rolling and controlled cooling,carbonitrides are dispersedly precipitated from microalloyed elements to form precipitation strengthening and grain refining strengthening,based on which work-hardening is produced by cold deformation,to further increase steel strength and reach required properties without quenching and tempering.Masteel developed innovat... |
