Based on the conservation laws of energy and mass, and taking into account the effect of chemical reaction between liquid titanium and zirconia ceramic mold on the concentration field and the temperature field, a comprehensive mathematical model for numerical simulation of heat and mass transfer has been established to study the interfacial reaction between liquid Ti and ZrO 2 ceramic mold. With the proposed model, numerical simulations were preformed to investigate the effects of pouring temperature and holding time on the oxygen concentrations and reactive layer thickness in metal. The results showed that both the oxygen concentration and the thickness of reactive layer in metal increase with the increase of the holding time and the pouring temperature. The development of reactive layer thickness with time consists of three stages: inoculation (0-1 s), linear increase (1-5 s) and parabolic increase (after 5 s).

A study on the interaction between TiAl alloy and zirconia was carried out in argon atmosphere. Themicrographic observations of the cross-section perpendicular to the interface were obtained using a scanning electronmicroscope with a dedicated energy dispersive spectrometer (SEM/EDS). The results showed that firstly TiAl alloyspreads on the ceramic surface, and then infiltrates into the pores between ceramic particles accompanied by a chemicalreaction. The whole ceramic mold is broken into tiny blocks. A multiple fission reaction mechanism was developed toexplain the interaction between TiAl alloy and zirconia.

采用挤压加轧制的方法制备Zn-0.75Cu-0.15Ti-0.3Mg合金板材,并探讨其组织演变过程、力学性能和耐腐蚀性能。结果表明:挤压变形后Zn-0.75Cu-0.15Ti-0.3Mg合金呈细小的等轴晶形貌,Zn基体中存在微米级TiZn_(3)和MgCuZn颗粒相以及纳米级CuZn_(5)颗粒相。轧制变形促使合金的晶粒发生长大,并且晶粒尺寸较为不均匀。随着轧制变形量的增大,基体形变诱导晶内更多MgCuZn颗粒相的析出。轧制变形后合金的强度和延伸率均呈降低趋势,抗拉强度从142.7 MPa降低到<110 MPa,这主要归因于晶粒的长大和脆性第二相的增多。不过,轧制变形有助于合金耐腐蚀性能的提高,轧制态合金具有较低的腐蚀电流密度(25.47×10^(-5)A/cm^(2))和较高的腐蚀产物层阻抗(166.8Ω·cm2)。

由于镁资源储量丰富、成本低廉,且金属镁具有理论体积比容量高(3833m Ah/cm^(3)),沉积/溶解过程中不易形成枝晶等优点,金属镁二次电池受到了研究者的广泛关注.然而,Mg^(2+)较大的极性导致其在多数锂离子电池正极材料中无法实现可逆脱嵌.主流无机电极材料普遍存在只能在较小电流密度下循环、动力学缓慢、制备工艺复杂等问题.相较而言,有机电极材料具有理论比容量高、结构多样易调控、资源丰富、环境友好、受离子半径和电荷影响小等优点,被认为是一种有潜力的电极材料.综述了近年来用于非水系镁二次电池有机正极材料的研究进展,讨论了不同类型有机正极材料的电荷存储机制及电化学性能,并总结了其面临的挑战、解决策略以及未来的发展方向.

以卤素氯离子为载荷离子的新概念氯离子电池(CIBs)被认为是“下一代”大规模、高安全电化学储能设备的有力竞争者。层状双金属氢氧化物(LDHs)因具有高的储氯容量与稳定的层状拓扑结构,被视为一类极具发展前景的CIBs正极材料。本工作以MOFs材料MIL-88A为模板前驱体,采用先水解后离子交换的两步法,制备了具有米粒形貌的氯离子插层NiFe LDH纳米多面体(g-NiFe-Cl LDH),其具有高于常规NiFe LDH纳米片两倍的比表面积。这种纳米多面体g-NiFe-Cl LDH材料能够克服一般LDHs纳米片层板间易堆积的本征缺陷,增大材料电化学活性位点暴露率,提高其与电解液的有效接触面积,促进氯离子扩散动力学,最终实现其储氯性能的强化。将g-NiFe-Cl LDH作为CIB正极材料时,电池表现出286.1 mAh/g的最大放电比容量,且在经过200次充放电循环后仍可保持155.3 mAh/g的稳定放电比容量,为常规NiFe-Cl LDH纳米片的两倍。同时,g-NiFe-Cl LDH基CIB的储能机理也被揭示:充电过程中,g-NiFe-Cl LDH正极中的氯离子从层间脱出,其主体层板中的双金属Ni^(3+)/Fe^(3+)被还原成Ni^(2+)/Fe^(2+)。考虑到LDHs材料简单的制备过程和高度可调的化学组分,本工作为设计具有高容量输出和长循环寿命的CIBs正极材料提供了新的思路。

针对重载齿轮用20CrNi2Mo钢热处理后易产生变形的问题,研究了热处理工艺对20CrNi2Mo钢性能的影响。结果表明:采用改进后的热处理工艺,试样的伸长率、断面收缩率、冲击韧度与原始工艺相比变化不大,抗拉强度、表面硬度、热处理畸变量均比用原始热处理工艺处理的性能要好,因此重载齿轮用20CrNi2Mo钢热处理时应采用改进后的热处理工艺代替原始工艺,为扩大20CrNi2Mo钢应用领域奠定了基础。
