| 摘 要： | 分析了定向凝固Fe-6.5％Si合金室温三点弯曲试样中的滑移带，采用EBSD方法测定了晶界位向差和晶粒取向.结果表明，在横向试样近下表面两个位向差为29.3°的晶粒中，滑移带在{001}面上分别与〈010〉方向成25°和60.7°.经分析，这两组滑移带都不属于{110}〈111〉滑移系，而可能属于{112}〈111〉或{123}〈111〉滑移系.

| Abstract: | The slip bands in specimens of directionally solidified Fe-6.5 %Si alloy bent at RT were observed and analyzed by electron back-scattering diffraction (EBSD). The results indicate that in two grains near the specimen bottom surface and with a misorientation of 29.3°, there are two sets of slip bands whose intersecting angles with 〈010〉 direction on {001} plane are 25° and 60. 7° respectively. The slip system corresponding to these two sets of slip bands has been proven most likely to be {112｝〈111〉or {123｝〈111〉 rather than {110}〈111〉. |
