| Abstract: | In order to optimize the EBSD scan area parameters based on the quantification of retained austenite,the relationship between the confidence interval and type A standard uncertainty and the scan area parameters were studied and discussed in detail.The research shows that according to comprehensively considering the main influencing factors such as the number of scanning fields(n≥6),confidence interval,type A standard uncertainty,and analysis time related to the optimization of scanning area parameters,the total scanning area must reach 65000μm2. |

| Keywords: | retained austenite EBSD scanning area confidence interval type A standard uncertainty |
