at 623 K. This is mainly attributed to rotational dynamic recrystallization (RDX) during the hot rolling. Key words: AZ31 magnesium alloy; texture; extruded sheet; inverse pole figure ... was measured by the linear intercept method. X-ray texture analysis was performed in a Rigaku D/max 2 500 VB+ diffractometer. Texture was presented by means of inverse pole figures which were calculated......
两种位向关系的描述方法的转换及其应用孟杨1,张文征1(1.北京市清华大学材料科学与工程系先进材料实验室)摘 要:本文推导了表征两套晶格间的位向关系的标识矢量方法到Euler角方法的转换关系,基于这个关系可以根据背散射电子衍射(EBSD)数据对少变体的系统进行拟合,获得各变体相互自洽的位向关系精确定量描述.本方法比高指数极图拟合的方法适用性更广,因为后者受最低变体数量的局限.以不锈钢的实验结果为例介绍了该方法的应用,检测出变体之间接近但不等于孪晶的取向差关系.关键词:位向关系； 背散射电子衍射； 极......
railways, it needs to carry out further investigations. 2 Numerical method Figure 1 is the installment photos of the wind sensors on the steel pole at the high-speed railway line in China. When the wind... together, which indicates that the coarse mesh is adequate and can be used for the follow-up research. Figure 6 shows the coarse mesh of the cross-section of the pole. In order to validate the accuracy......
warm rolled at 300 °C because of higher density of shear bands. The warm rolled ZK60 alloy sheet exhibited strong (0002) pole texture, the intensity of (0002) pole figure decreases with the increasing of rolling temperature and the basal pole tilted slightly to the transverse direction after warm rolling. Key words: warm rolling; microstructure; macrotexture; pole figure; ZK60 alloy 1 Introduction......
