Strengthening due to precipitation of Cu in the αFe matrix is an important phenomenon utilized in the design of HSLA steels. In the present work, the microstructure of supersaturated solid solution in Fe118%Cu binary alloy was investigated by means of high resolution electron microscopy. The results indicated that the solid solution was heterogeneous, there were lots of Cu atom clusters, which consisted of diffractive stripe microstructure similar to twin crystal. Orientation deviation was observed between two (110)α planes in diffractive stripes, which results in light and shade contrast. Furthermore, formation mechanisms of the nanometre stripe microstructure were discussed in terms of the interaction of Cu and Fe atoms in the FeCu binary alloys.

导读内容
本钢炼铁厂265 m2烧结机生产所需要的含铁原料比较复杂，一次配料料种较多，且烧结含铁原料是由本钢原料厂二车间供料，原料质量的不稳定，会影响烧结矿质量的提高和新一号高炉的强化及高炉技术指标的改善。本钢质量管理中心驻冷烧检查站加强了对烧结配料所需原料及对冷烧结矿成品检验采制样代表性的研究，采取了一些改进措施，达到了良好的效果。含铁料成分稳定率、烧结矿各项质量和技术指标在稳步地提高。下面，对本钢质量管理中心驻冷烧检查站就提高采样及检验过程的准确性所采取的措施和办法进行说明。
烧结矿采样是半自动采样，每两小时采样一次，作为一个批次，来代表整个2h烧结矿的成份。
