The fine structure of hydrogen storage alloy powders MlNi4.3-xCoxMn0.4Al0.3(x=0.75, 0.45, 0.10; Ml: La-rich misch metal) prepared by rapidly solidifying gas atomization was investigated using a Rietveld analysis method. Two sets of CaCu5-type crystal constants were observed in the studied alloys and one set was larger than the other. With decreasing powder radius the solidification rate of powder increased, and so did the percentage of a particle part with larger crystal constants. The reason why there were two sets of crystal constants might be the difference of solidification rate between the outside and inside of a particle.

　　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。
