本文对铝合金板材拉伸变形时橘皮成因的研究进展进行了评述。首先展示了有无橘皮板材在各种检测仪器下拉伸变形前后的表面形貌、表面滑移带、粗糙度和拉伸断口的形貌,并展示了纳米硬度的测量结果和表征。进一步介绍了最近关于橘皮形成的电子背散射衍射技术(EBSD)的研究成果和X射线对有无橘皮样品的织构测量结果,结合样品的显微组织和力学性能深入分析了橘皮的成因。一系列的结果表明,拉伸变形以后表面橘皮的出现与拉伸变形过程中产生的织构密切相关,而织构的生成又与拉伸过程中晶粒变形的不均匀性有关;晶粒的大小将明显影响变形的不均匀性和织构的生成,粗晶粒比细晶粒更容易产生不均匀变形、晶粒转动和织构,从而导致拉伸变形后生成表面橘皮。由此介绍了粗晶粒和细晶粒拉伸变形后表面状态的示意模型,同时建议对橘皮的形成进行进一步的研究和分析,以完善橘皮成因的定量描述。

Methyl acetate is considered low toxicity volatile solvent produced either as a by-product during methanol carbonylation or via acetic acid esterification with methanol. In both cases, pure methyl acetate has to be isolated from the reaction mixture. Simulation of methyl acetate separation from its mixture with methanol by extraction distillation was carried out in ASPEN+ software. In total three case studies were assumed using two different extraction solvents and two solvent regeneration strategies. In case A, novel extraction solvent 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ionic liquid, was considered. Raw material separation was achieved in an extraction distillation column while the solvent regeneration was accomplished in a second distillation column in this case. In case study B, the same extraction solvent was used; however, its regeneration was carried out in a single-effect evaporator. Dimethyl sulfoxide was the second extraction solvent selected. Its use in methyl acetate-methanol separation is presented in case study C. As high purity of dimethyl sulfoxide was required for the methyl acetate-methanol azeotrope breaking, its regeneration was carried out in the second distillation column only. To simulate the ternary methyl acetate–methanol–extraction solvent mixtures separation, vapor–liquid equilibrium was predicted based on the NRTL equation. Further, unknown properties of the considered ionic liquid and variation of these properties with temperature were predicted and introduced into the ASPEN+ components properties database. Based on these data, optimum operation parameters of the respective separation equipment were established. In all case studies, the same condition had to be fulfilled, namely minimum methyl acetate content in the distillate from the extraction distillation column of 99.5mol-%. Results of simulations using the respective optimum operation parameters were employed in the economic evaluation of the three separation unit designs studied. It was found that the least energy-demanding design corresponds to the case study B in terms of both capital as well as operation expenses.
