J. Cent. South Univ. Technol. (2011) 18: 1068-1073 DOI: 10.1007/s11771-011-0805-4 Degradation of chlorothalonil by ultrasonic irradiation: Kinetics and impact factors GUO Hong-guang(郭洪光), GAO Nai... and Springer-Verlag Berlin Heidelberg 2011 Abstract: Factors on degradation of chlorothalonil (CLT) in water by high frequency ultrasonic irradiation were investigated. The effects of initial......
Fig. 3(a)). The reason is that the quantity of atomic diffusion is not enough and the dissolution reaction is insufficient between the molten interlayer and the master alloys. When the brazing... of the joints are remarkably affected by the brazing parameters. When the brazing parameters are 960 °C and 10 min, the dissolution reaction is insufficient and no Ti-Ni-Al alloy forms at the reaction layer......
3.2.1 Corroded Ti/TiCuNi/Ti joints SEM images did not exhibit any visible preferential dissolution at the brazing interface of the Ti/TiCuNi/Ti joints (Fig. 4). Correspondingly, EDS analysis did...-rich and Ti phases formed at the interface and commercially pure Ti base metal. However, no significant differences were observed between the joint system and the base material when brazing......
Fabrication of carbon nanotubes reinforced AZ91D composites by ultrasonic processing LIU Shi-ying(刘世英)1, 2, GAO Fei-peng(高飞鹏)1, 2, ZHANG Qiong-yuan(张琼元)1, 2, ZHU Xue(朱 雪)1, 2, LI Wen-zhen(李文珍)1... intensity ultrasonic dispersion processing. The microstructures and mechanical properties of the nanocomposite were investigated. The results show that CNTs are well dispersed in the matrix and combined......
