| 1 | Al/SiC_p金属基复合材料搅拌摩擦焊工艺参数的多目标优化(英文)显示文摘碳化硅颗粒(SiC_p)增强铸造铝基复合材料(MMC)在制造高比强、高温性能好和耐磨的轻质结构件中得到广泛应用。焊接接头的性能取决于搅拌摩擦焊(FSW)的工艺参数。研究铸造AA6061/20%SiC_p(体积分数)金属基复合材料焊接接头的抗拉强度、缺口拉伸强度和硬度,建立搅拌摩擦焊工艺参数(刀具转速、焊接速度和轴向力)与接头性能(抗拉强度、缺口拉伸强度和焊点硬度)之间的关系,确定最佳的焊接条件,以最大限度地提高接头的力学性能。结果表明,当搅拌针转速为1370 r/min、焊接速度为88.9 mm/min和轴向力为9.6 kN时,接头的最大抗拉强度、缺口拉伸强度和硬度分别为265 MPa、201 MPa和HV114。 | P.PERIYASAMY B.MOHAN V.BALASUBRAMANIAN S.RAJAKUMAR S.VENUGOPAL | 2013 | Transactions of Nonferrous Metals Society of China2013，23，4： | 3 |
| 2 | Non-spherical aluminum nanoparticles fabricated using picosecond laser ablation显示文摘We report the picosecond laser ablation of aluminum targets immersed in a polar organic liquid(chloroform,CHCl3)with^2 ps laser pulses at an input energy of^350μJ.The synthesized aluminum nanoparticles exhibited a surface plasmon resonance peak at^340 nm.Scanning electron microscopy images of Al nanoparticles demonstrated the spherical morphology with an average size of(27±3.6)nm.The formation of smaller spherical Al nanoparticles and the diminished growth could be from the formation of electric double layers on the Al nanoparticles.In addition to spherical aluminum nanoparticles,triangular/pentagonal/hexagonal nanoparticles were also observed in the colloidal solution.Field emission scanning electron microscopy images of ablated Al targets demonstrated laser induced periodic surface structures(LIPSSs),which were the high spatial frequency LIPSSs(HSF-LIPSSs)since their grating period was^280 nm.Additionally,coarse structures with a period of^700 nm were observed. | A.Brahma Swamulu S.Venugopal Rao G.Krishna Podagatlapalli | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，7： | 2 |
