| 1 | X-ray Peak-Shift Determination of Deformation Fault Probability in Fe-Mn-Si Alloys显示文摘The X-ray diffraction peak-shift method was introduced into the determination of deformation fault probability (α)of Fe-Mn-Si alloys with various Mn contents and thermomechanical cycling numbers. The precise lattice constantsrequired were obtained by numerical calculation instead of using standard sample without any fault. The influenceof internal stress on the determined α has been evaluated, and the caused relative error was determined as about 4%and thus negligible. The results show that the deformation fault probability increases with decreasing Mn-content andincreasing cycle number, which are qualitatively consistent with those results of Psf determined by peak-broadeningmethod. | YonghuaRONG GangHE ZhenghongGUO ShipuCHEN T.Y.Hsu(XUZuyao) | 2002 | Journal of Materials Science & Technology2002，18，5： | 4 |
