| 1 | Multiscale and multiphysics explorations of the transient deposition processes and additive characteristics during laser 3D printing显示文摘Laser directed energy deposition(DED)involves complex physical processes,and the trial and error examinations are time consuming and cost expensive.The research paradigm can be reshaped using advanced phenomenological models via computing the spatiotemporal variations of the build features.In this work,multi-layer and multi-track laser DED of Ti-6 Al-4 V were systematically explored on multiple scales including the 1D track,the 2D layer and the 3D full build considering the complex transport of energy,mass,and momentum in the moving freeform molten pool.The results showed that convex,nearflat,and wavy builds were generated using gradually larger hatch spacings.The profiles of individual tracks and layers were extracted through the unique advantages of the model.The individual tracks exhibited various patterns and rotated with specific inclinations to form distinct layer profiles.The net increments of the deposit generated upon the printing of a new track during the continuous deposition process showed that the smaller hatch spacing caused higher overlap rate of horizontally adjacent tracks but lower remelting rate of vertically adjacent tracks in neighboring layers.The 3D numerical model was validated with corresponding experiments for various process conditions.The scientific findings can provide useful insights for further researches of DED. | H.L.Wei F.Q.Liu L.Wei T.T.Liu W.H.Liao | 2021 | Journal of Materials Science & Technology2021，，18： | 5 |

| 6 | 由水溶性聚合物制备多功能碳纳米纤维垫显示文摘聚合物前驱体成本高、碳化后处理工艺中有机溶剂的应用,以及能源消耗等问题,限制了碳纤维在日常生活中的应用。采用离心力纺丝技术及在酸蒸气中脱水的方法制备非织造纳米纤维垫,并采用低温碳化工艺(t<800℃)制备多功能碳纳米纤维。这种方法可以制备微孔与中孔的多孔非织造碳纤维织物或纱线。纤维的直径可在几百纳米到几微米之间变化。热物理和微观结构表征表明,化学和热处理过程中的碳化形成了石墨。所制备的纤维表现出较高的导电性和比表面积,以及良好的热稳定性、疏水性和亲油性。 | L.D.Cremar J.Acosta-Martinez A.Villarreal A.Salinas L.Wei Y.B.Mao K.Lozano 钟晓慧(译) 王依民(校) | 2016 | 国际纺织导报2016，44，11： | 0 |
