| 1 | Complex(Mn,X)S compounds-major sites for graphite nucleation in grey cast iron显示文摘Despite the cubic system,the ability of sulphides to nucleate graphite can be enhanced by inoculating elements which transform them in complex compounds with a better lattice matching to graphite,a low coagulation capacity,good stability and adequate interfacial energy.(Mn,X)S compounds,usually less than 5.0μm in size,with an average 0.4-2.0μm well defined core(nucleus),were found to be important sites for graphite nucleation in grey irons.A three-stage model for the nucleation of graphite in grey irons is proposed:(1)Very small micro-inclusions based on strong deoxidizing elements(Mn,Si,Al,Ti,Zr)are formed in the melt;(2)Nucleation of complex(Mn,X)S compounds at these previously formed micro-inclusions;(3)Graphite nucleates on the sides of the(Mn,X)S compounds with lower crystallographic misfit.Al appears to have a key role in this process,as Al contributes to the formation of oxides in the first stage and favors the presence of Sr and Ca in the sulphides,in the second stage.The 0.005-0.010%Al range was found to be beneficial for lower undercooling solidification,type-A graphite formation and carbides avoidance. | Iulian Riposan Mihai Chisamera Stelian Stan Doug White | 2009 | China Foundry2009，6，4： | 4 |

| 4 | 镀锌钢构架在北美住宅环境中的耐蚀性能显示文摘钢结构住宅是未来住宅建筑的发展方向之一,而住宅钢结构防腐蚀寿命也成为钢结构住宅推广的关键因素之一。国际铅锌研究组织项目"住宅镀锌钢构架在实际住宅环境下的耐蚀性研究"通过选取北美4种典型的住宅环境,对锌及锌合金镀层钢铁试样进行了连续7年的暴露试验,并对镀锌钢构架在不同住宅环境中的腐蚀速率进行了评估。公布的研究结果表明,镀层质量为200-270 g/m^2的镀锌钢以及质量相当的锌合金镀层钢试样在4种环境下腐蚀速率均非常小,以所有试样中的最大腐蚀速率来评估镀锌及锌合金钢试样在4种环境下的使用寿命可达258-964年,平均574年。在住宅设计使用年限内,采用镀锌钢结构不会因腐蚀而使得钢结构性能降低。镀锌钢可以作为一种可持续性的建筑材料使用。 | 孔纲 刘玲艳 Rob White Doug Rouke | 2010 | 腐蚀与防护2010，31，6： | 1 |
