| 1 | Bi和Sr改性Al-7Si-0.4Mg合金显微组织的影响(英文)显示文摘研究单独添加Bi和联合添加Bi与Sr在不同凝固条件下对Al-7Si-0.4Mg合金中共晶硅结构的影响。结果表明:添加Bi对共晶硅有细化作用,其细化能力随着Bi质量分数(在<0.5%范围内)的增加而增强。当Bi添加到Sr改性的合金中时,为了得到充分的共晶硅改性,较高的Sr/Bi质量比(至少0.45)是必要的。 | S.

| 2 | Effect of Primary and Eutectic Mg_2Si Crystal Modifications on the Mechanical Properties and Sliding Wear Behaviour of an Al–20Mg_2Si–2Cu–xBi Composite显示文摘This work investigated the microstructure evolution, tensile, impact, hardness, and sliding wear properties of an Al–20Mg_2Si–2Cu in situ composite treated with different Bi contents. The desired modification of primary Mg_2 Si particles was achieved with the addition of 0.4 wt% Bi. Increasing Bi beyond 0.4 wt%resulted in a loss of modification, possibly due to the formation of Al_8 MgB iS i4 compound before the precipitation of the primary Mg_2 Si. Additionally, the structure of the pseudo-eutectic Mg_2 Si was transformed from plate to fibrous, which was consistent with decrease of growth temperature extracted from the cooling curve thermal analysis. Addition of Bi had an effect on the morphology of Al_5 Fe Si(β), Al_2Cu(θ) and Al_5Cu_2Mg_8Si_6(Q) intermetallic compounds. The tensile strength, elongation percentage, impact toughness, and hardness increased by 6%, 13%, 75%, and 23%, respectively, due to modification of both the primary and eutectic Mg_2 Si crystals. The tensile and impact fracture surfaces showed fewer decohered particles in the Bi-treated composite. The enhancement in wear resistance of the Bi-treated composite could be attributed to solid lubricant function of insoluble soft Bi phase and modification effects on Mg_2 Si particles. | Saeed Farahany Hamidreza Ghandvar Nur Azmah Nordin Ali Ourdjini Mohd Hasbullah Idris | 2016 | Journal of Materials Science & Technology2016，32，11： | 7 |
| 3 | 涂层厚度对消失模铸Al-Si-Cu合金铸件的影响(英文)显示文摘对Al-Si-Cu合金进行消失模铸造,研究涂层厚度对Al-Si-Cu合金铸件缺陷、孔隙率和共晶硅间距的影响。结果表明,提高涂层浆料黏度和延长浸渍时间对铸件的完整性和显微组织有影响。薄的涂层有利于模腔充填性能的改善、显微组织的细化和低孔隙度高质量铸件的获得。 | Majid KARIMIAN Ali OURDJINI Mohd HASBULLAH IDRIS Hassan JAFARI | 2012 | Transactions of Nonferrous Metals Society of China2012，22，9： | 5 |
| 4 | Effect of thermomechanical treatment on microstructure and hardness behavior of AZ63 magnesium alloy显示文摘Due to their high specific strength and low density, magnesium alloys are widely used in many weight-saving applications. This research is aimed at investigating the microstructure and hardness of commercial AZ63 alloy specimens subjected to two different thermomechanical treatments (TMTs). For the first TMT, after solution treated at the temperature of 380 ℃ for 20 h, AZ63 alloy specimens were 5% cold worked by rolling process followed by ageing at the temperatures of 150 ℃ and 250 ℃ for 3, 9 and 25 h. In the second TMT, the specimens were solution treated at the temperature of 380 ℃ for 20 h, underwent 2% cold worked and quenched in water of 0 ℃. Half of the specimens were then 2% cold worked whilst the rest were rolled to 8% cold worked. All the specimens were then aged at the temperatures of 150 ℃ and 250 ℃ for 3, 9 and 25 h. Optical microscope was used to analyze the microstructures of the specimens. Hardness test was too conducted to measure the effect of the treatments on the specimens. Results show that two-step aging enhances the hardness of the specimens due to the distribution of fine β-phase (Mg17Al12) in the alloy matrix. The results also reveal that, the best hardness from the first TMT was produced by specimen that was pre-aged at 150 ℃ whereas, in the second TMT, aging at 250 ℃ exhibited the best hardness values. | H.

| 5 | Influence of Gating System,Sand Grain Size,and Mould Coating on Microstructure and Mechanical Properties of Thin-Wall Ductile Iron显示文摘Two gating systems namely stepped and tapered runners were used to cast strip samples with different thicknesses by CO2/silicate process using sand grain sizes of AFS 151 and 171.To assess the effect of mould coating on the properties of thin-wall ductile iron,half of the moulds were coated whilst the rest were not coated.Molten metal with the carbon equivalent of 4.29% was prepared and poured at 1450 ℃.Microstructure of the specimens was analyzed by optical and scanning electron microscopes.Count,area fraction,roundness and diameter of the graphite nodules of the samples were measured by image analyzer.Brinell hardness and tensile tests of all the samples were also conducted.The results show that by using stepped runner gating system with uncoated and coarse sand mould,roundness and count of the graphite nodules decrease whereas diameter and area fraction increase.Although fine sand and coated mould cause longer distance of molten metal travel,hardness and strength of the samples decrease. | Hassan Jafari Mohd Hasbullah Idris Ali Ourdjini Majid Karimian Gholamhassan Payganeh | 2010 | Journal of Iron and Steel Research(International)2010，17，12： | 2 |
