A quantitative and automated phase analysis of dual-phase (DP) steel using electron backscatter diffraction (EBSD) was attempted. A ferrite-martensite DP microstructure was produced by intercritical annealing and quenching. An EBSD map of the microstructure was obtained and post-processed for phase discrimination. Band slope (BS), which was a measure of pattern quality, exhibited much stronger phase contrast than another conventional one, band contrast. Owing to high sensitivity to lattice defect and little orientation dependence, BS provided handiness in finding a threshold for phase discrimination. Its grain average gave a superior result on the discrimination and volume fraction measurement of the constituent phases in the DP steel.
尝试使用电子背散射衍射（EBSD）对双相（DP）钢进行定量和自动化的相分析。通过中间临界退火和淬火生产出铁素体-马氏体 DP 微观结构。获得了微观结构的 EBSD 图谱，并进行了后处理以进行相鉴别。带斜率（BS）是图案质量的一种度量，它比另一种传统的带对比度具有更强的相位对比度。由于对晶格缺陷具有高灵敏度和小的取向依赖性，BS 在为相鉴别找到阈值时提供了便利性。其晶粒平均值在 DP 钢中组成相的鉴别和体积分数测量方面给出了更好的结果。
