| 摘要: |
| 以Mn-Mo-Nb-B微合金系统为研究对象,利用动态连续刚度测量纳米压痕技术,结合低碳微合金钢中针状铁素体组织的特点,分析针状铁素体组织的纳米硬度-位移曲线,计算针状铁素体组织的基体纳米硬度。结果表明:针状铁素体组织的基体纳米硬度为2.14GPa,波动为29.37%,与动态CSM方法提供的原始结果相比,通过对特定显微组织的纳米硬度-位移曲线分析而得出的纳米硬度数据的波动显著减小。 |

| Abstract: |
| Dynamic continuous stiffness measurement (CSM) nanoindentation method was applied to measure nano hardness of acicular ferrite in low carbon microalloying steels (Mn-Mo-Nb-B).The nano hardness-displacement curves of acicular ferrite were analyzed, and the matrix hardness was calculated.The results show that the matrix nano hardness of acicular ferrite microstructure is 2.14GPa, and the fluctuation is about 29.37%.Compared with the original results gained by dynamic CSM, the fluctuation obtained from the nano hardness-displacement curves of acicular ferrite significantly reduced. |
