The present paper investigates the bulk metallic,lass formation ill Cu-Zr-Al and Cu-Zr-Ti ternary systems by using the cluster line criterion. The binary basic Clusters are first selected for constructing cluster lines. Three cluster selection rules are proposed: topologically dense packing, chemical short-range order and composition distance to deep eutectics. Three Cu-Zr clusters Cu8Zr5, Cu6Zr5 and Cu5Zr6 are selected according to the three rules. The bulk metallic glass-forming ranges in these two systems are determined. The thermal characteristic parameters of the Cu-Zr-Al BMGs on every composition line increase with increasing Al content and decrease with increasing Ti content in the Cu-Zr-Ti glass-forming range. The optimum bulk amorphous compositions in the Cu-Zr-Al system are Cu58.1Zr35.9Al6 and Cu39.7Zr47.1Al13.2, respectively, located in Cu8Zr5-Al and Cu5Zr6-Al Cluster lines. In the Cu-Zi-Ti system, the Cu64Zr28.5Ti7.5 composition with the largest T-g/T-l is located in Cu9Zr4-Ti cluster line and the Cu57.6Zr32.4Ti10 composition with the largest glass-forming ability is located in Cu64Zr36-Ti line.

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。
