    • 摘要: 采用涂盐法研究表面涂覆有90%(质量分数,下同)Na2 SO4+10%NaCl混合盐(750°C熔融态)和纯Na2 SO4盐(750°C固态)的第二代镍基单晶高温合金DD421在750°C大气环境下(无SOx气氛)的热腐蚀行为.结果表明:在熔融混合盐腐蚀介质中,硫化反应主要由液相熔融盐侵蚀所导致.热腐蚀100 h后合金腐蚀产物主要为典型的简单氧化物(Al2 O3,Cr2 O3,TiO2)以及Ni/Cr/Ti的硫化物.而在纯Na2 SO4固态盐热腐蚀实验中,热腐蚀100 h后合金腐蚀产物与混合盐实验中的产物基本相同,但其腐蚀层厚度相对更薄,硫化物尺寸相对更大.结合热力学和微观组织分析,本研究明确了在无SOx气氛的腐蚀环境下合金元素能够与固态Na2 SO4盐发生硫化反应.

    • 摘要: The catalysts FeNaY-10,FeNH4Y-10 and FeHY-10 with 10%(w) of Fe loading were prepared by solid state reaction process using zeolite NaY,NH4Y and HY as supporter and acetylacetone iron as iron source. The degradation effects of reactive brilliant blue (KN-R) on these catalysts were studied and that on FeHY-10 was the best. FeHY-10 was characterized by XRD and FTIR and the results showed that the crystal structure of FeHY-10 still maintained the unique pore structure of Y zeolite and iron species well dispersed on the surface of Y zeolite. The optimum conditions for catalytic degradation of KN-R were as follows:mass concentration of KN-R solution 300 mg/L,KN-R solution volume 50 mL,solution pH 2,amount of catalyst FeHY-25 (with 25% (w) of Fe loading) 0.281 3 g,H2O2 mass concentration 6.356 g/L,degradation temperature 35 °C and degradation time 140 min. Under these conditions, the the degradation rate of KN-R on catalyst FeHY was 97.4%.%分别以NaY、NH4Y和HY沸石为载体,以乙酰丙酮铁为铁源,采用固态反应法制备了铁负载量均为10%(w)的FeNaY-10、FeNH4Y-10和FeHY-10催化剂.考察了各催化剂对活性艳蓝(KN-R)的降解效果,其中FeHY-10的催化降解效果最佳.采用XRD和FTIR技术对FeHY-10催化剂进行表征.表征结果显示,FeHY催化剂晶体结构仍然保持了Y分子筛特有的孔道结构,铁物种在Y 分子筛表面高度分散.催化降解实验表明,催化降解KN-R的最佳工艺条件为KN-R溶液(质量浓度为300 mg/L)加入量为50 mL、溶液pH为2、催化剂FeHY-25(铁负载量为25%(w))加入量为0.2813 g、H2O2质量浓度为6.356 g/L、降解温度为35 °C、降解时间为140 min,在此工艺条件下FeHY催化剂对KN-R的降解率为97.4%.

    • 摘要: Based on the empirical electron theory (EET) of solids and molecules, the relationship between the interface coefficient and the broken bonds during the atomic dissolution of the same kind of atoms was discussed:the larger the energies required to break bonds are, the smaller the interface coefficients are. Then, the bond breaking energies of Cu and Ti atoms at the low index crystal planes of CuTi2, e.g., (101), (100), (001), (110) and (013) were calculated. The calculated results indicate that the bond breaking energies change with the crystal orientations, and the order of the interface coefficients of Cu and Ti atoms from large to small is determined as follows:(101), (100), (001), (110), (013), which is valuable to analyze the morphology evolution in the CuTi2/Zn solid­state reaction system or other systems using CuTi2 substrate.%  运用固体与分子经验电子理论(EET)研究固态反应界面系数与原子脱溶所需断裂的共价键之间的关系:同类原子脱溶所需的共价键断键能越高,界面系数越小。以 CuTi2固态反应基体为例,计算 CuTi2固态反应基体中(101)、(100)、(001)、(110)和(013)等低指数晶面上原子脱溶所需的共价键断键能。计算结果表明,不同晶体取向的原子脱溶所需的共价键断键能不同。通过 Cu 原子和 Ti 原子的界面系数由大到小的顺序均为(101)、(100)、(001)、(110)、(013),该结果对于 CuTi2/Zn 反应体系及其他 CuTi2反应体系固态反应区的结构演变分析具有重要价值。

    • 摘要: A 0.7 mm-thick wavy γ-TiAl sheet with fully lamellar microstructure was fabricated by hot pressing Ti/Al alternate foils with heat treatment of 640 °C,15 h+850 °C,35 h+1350 °C,2 h.The intermetallic compounds formed during heat treatments were identified by scanning electron microscopy (SEM) and X-ray diffraction (XRD).TiAl3 was the only observed phase at the Ti/Al interface when Al foils were not consumed.After being annealed at 850 °C for 35 h,the microstructure was composed of α-Ti,α2-Ti3Al,γ-TiAl and TiAl2.A fully lamellar microstructure formed after annealing at 1350 °C.Most of the angles between the lamellar interface and the sheet plane are below 30°.Using thinner starting foils is favorable to produce sheets with fine microstructure.%用热压逐层叠置的Ti/Al箔的方法制备具有全片层结构的γ-TiAl波纹板.热处理工艺为640°C,15h+850°C,35 h+1350°C,2h.用扫描电镜(SEM)和X射线衍射(XRD)分析热处理过程中产生的金属间化合物相.在Al箔完全消耗之前,Ti/Al界面仅有TiAl3相生成.在850°C热压35 h后,基体由α-Ti,a2-Ti3Al,γ-TiAl和TiAl2相组成.冷却得到全片层结构,大部分片层与板面的夹角小于30°.采用较薄的原料箔可以获得相对细小的微观组织.
