摘　　要：本研究旨在探究合金元素在金属材料组织演变中的作用及其对性能的影响,特别是在高强微米级不锈钢纤维的制备过程中。通过精心设计的实验,选取316L不锈钢作为基体材料,并添加铝(Al)、钛(Ti)等合金元素,系统地观察了合金元素对材料相组成、晶粒尺寸、析出相形态及分布的影响。实验结果显示,合金元素的添加显著改变了材料的组织结构,进而影响了其强度、韧性、硬度和耐腐蚀性,为开发高性能金属材料提供了重要的理论依据和技术指导。The purpose of this study was to investigate the role of alloying elements in the microstructure evolution of metal materials and their effects on properties,especially in the preparation process of high-strength micron grade stainless steel fibers.The effects of 316L stainless steel on the phase composition,grain size,morphology and distribution of the precipitated phase were systematically observed by using aluminum(Al),titanium(Ti)and other alloying elements.The experimental results show that the addition of alloying elements significantly changes the structure of the material,and then affects its strength,toughness,hardness and corrosion resistance,which provides an important theoretical basis and technical guidance for the development of high-performance metal materials.
