钢铁材料是迄今为止最重要可回收利用的结构材料。铁素体是钢铁材料中的一种重要组织。铁素体的表征与分析对于理解钢铁材料中的组织演变、物理性能和力学性能等有重要的作用。通常观察组织形貌的方法是在二维截面上进行。随着计算机和仪器设备的发展,材料组织的三维表征和定量分析已经成为理解材料结构和相变的一种有效手段。本文评述了钢铁材料中的晶界铁素体、晶内铁素体、针状铁素体和退化铁素体的三维表征和分析,以进一步了解钢铁材料中铁素体的形态特征和组织演变过程。
Steel is by far the most important recyclable structural material. Ferrite is an important organization in steel materials. The characterization and analysis of ferrite plays an important role in understanding the microstructure evolution, physical properties and mechanical properties of steel materials. The usual way to observe the topography of a tissue is in two-dimensional sections. With the development of computer and instrumentation, the three-dimensional characterization and quantitative analysis of material organization has become an effective means to understand the structure and phase transition of materials. This paper reviews the three-dimensional characterization and analysis of grain boundary ferrite, intragranular ferrite, acicular ferrite and degenerate ferrite in steel materials to further understand the ferrite morphology and microstructure evolution in steel materials .
