Nd对Mg-11Li-3Al- -2Zn-0.2Zr合金组织、力学性能及腐蚀行为的影响

雷雪 Lei Xue 王日初 Richu Wang 彭超群

研究稀土Nd对均匀化态Mg-11Li-3Al-2Zn-0.2Zr合金组织、力学性能及腐蚀行为的影响.通过真空感应熔炼制备镁锂合金铸锭, 经均匀化处理(280 ℃, 24 h)得到均匀化态Mg-11Li-3Al-2Zn-xNd-0.2Zr(x=0, 0.5, 1.0, 1.5)合金.采用XRD和SEM分析合金的显微组织, 并对合金进行拉伸试验和断口分析.采用电化学法和析氢失重法研究合金在3.5 %NaCl溶液中的腐蚀行为.结果表明:Mg-11Li-3Al-2Zn-0.2Zr合金主要含有β-Li、AlLi、MgLi2Al相, Nd的加入使合金中形成NdAl3相.随着Nd含量的增加, 合金的强度和塑性呈先增大后降低的趋势. Mg-11Li-3Al-2Zn-1Nd-0.2Zr合金表现出较优的力学性能, 其抗拉强度和延伸率相对于Mg-11Li-3Al-2Zn-0.2Zr合金分别提高了28.8 %和51.3 %.稀土Nd的添加使合金的耐蚀性能提高.

Experimental investigation on forge forming process of spray deposited blanks of rapidly solidified AlFeX heat-resistant aluminum alloy

Materials Science and Technology (2006)

Richu Wang

Spray deposited blanks of rapidly solidified AlFeVSi alloy are demanded to compact by using of hot-forge process at 450℃.Deformation capability and forge failure behavior of the as-deposited and as-compacted blanks were studied by forge test in different orientations.The full dense forge pieces of spray deposited Al-9.20Fe-1.37V-2.30Si alloy were fabricated through steel package forge process.Effect of hot-forge deformation on microstructures and mechanical properties of spray deposited AlFeVSi alloy was studied by means of optical microscopy,transmission electron microscopy,scanning electron microscopy and measure of tensile properties.The results show that,spray deposited AlFeVSi alloy blanks can be compacted to realize metallurgical binding state through hot-forge deformation.Single-pass reduction ratio of the hot compacted billets of spray deposited AlFeVSi alloy may be considered as 20-40%.During forge deformation,it is necessary to load the forging force in perpendicular to the original depositing surface of billet,and to add plastic package to limit open deforming of the side-surface.By using steel package forge process,the forge pieces of spray deposited Al-9.20Fe-1.37V-2.30Si alloy with excellent mechanical properties of σ_(0.2)=431MPa,σ_b=462MPa and δ=9.6% at room temperature,and σ_(0.2)=187MPa,σ_b=210MPa and δ=10.2% at high temperature of 350℃ can be obtained in the condition of small compressing deformation.

U-Shaped Relationship between Years of Residence and Negative Mental Health Outcomes among Rural-to-Urban Children in Migrant Schools in Beijing, China: The Moderating Effects of Socioeconomic Factors

Frontiers in Public Health (2017)

Jin Cheng Richu Wang Xing Yin Lin Fu Zheng-kui Liu

This study aimed to test the relationship between length of residence and mental health in a school-based sample of migrant children who studied in migrant schools.A total of 7,296 rural-to-urban migrant children were recruited from 58 schools in Beijing and assessed by the State-Trait Anxiety Inventory and Children's Depression Inventory.A quadratic relationship was found between mental health and length of residence. The results suggested that the scores for anxiety and depression were high during the initial resettlement after migrating and then decreased. However, after approximately 8 years, the scores increased. Our findings also showed a significant moderating effect of family socioeconomic status on the relation between mental health and length of residence.This study provided empirical evidence for a better understanding of psychosocial factors on the mental health of migrant children during the process of urbanization in China.
