| 1 | ECAP对A390铝合金显微组织和拉伸性能的影响(英文)显示文摘研究等径角挤压(ECAP) A390铝合金的抗拉强度和伸长率,揭示其显微组织和拉伸性能之间的关系。采用光学显微镜(OM)、扫描电镜(SEM)和能谱仪(EDS)对样品的显微组织进行分析。力学性能测试结果表明,经过3道次挤压后,材料的极限抗拉强度(UTS)从铸态的142 MPa提高到275 MPa。与铸态样品相比,当ECAP道次增加到4时,材料的伸长率显著提高。研究发现,随着ECAP道次的增加,材料的强度和伸长率提高,这是因为颗粒的均匀分布、颗粒尺寸的减小和空位的消除,尤其是与原始硅颗粒相邻的空位的消除。断口分析结果表明,当ECAP的道次增加到4时,在合金中形成均匀的圆形韧窝,合金断裂机理由铸态时的脆性断裂转变为韧性断裂。 | Esmaeil DAMAVANDI Salman NOUROUZI Sayed Mahmood RABIEE Roohollah JAMAATI | 2019 | Transactions of Nonferrous Metals Society of China2019，29，5： | 7 |
| 2 | 原位AA2024-Al_(3)NiCu复合材料的非等温时效行为显示文摘研究非等温时效处理对搅拌铸造原位AA2024-Al_(3)NiCu复合材料显微组织和力学性能的影响。在搅拌铸造过程中加入3%(质量分数)的镍粉,铸造后在500℃均匀化热处理24 h,得到Al_(3)NiCu金属间化合物。光学显微镜和扫描电镜观察结果表明,经非等温时效处理后,S-Al_(2)CuMg析出相得到细化,在枝晶之间形成该析出相的贫相区。在搅拌铸造过程中添加镍,降低S-Al_(2)CuMg析出相的析出速率及其在非等温时效处理过程中对复合材料的强化作用。含3%镍的样品在250℃非等温时效处理后可获得最大的硬度、极限抗拉强度和韧性,分别为:(121.30±4.21) HV,(221.67±8.31) MPa和(1.67±0.08) MJ/m^(3)。与不含镍的AA2024铝合金相比,AA2024-Al_(3)NiCu复合材料的最大硬度和极限抗拉强度分别降低6%和4%。 | Ramezanali FARAJOLLAHI Hamed JAMSHIDI AVAL Roohollah JAMAATI | 2022 | Transactions of Nonferrous Metals Society of China2022，32，7： | 2 |
