Fabrication of Lead Zirconate Titanate Powder Using Ultrasonic Ball Milling Technique Wandee Thamjaree1,W. Nhuapeng1,T. Tunkasiri1 (1.Department of Physics, Faculty of Science, Chiang Mai University, Chiang Mai 50200, Thailand) 摘要:In this research, the ultrasonic ball milling technique has been used to fabricate lead zirconate titanate (PZT) ceramics.PZT with the composition nearly......
together. The milling speed was 350 r/min and the duration time was 5, 10, 20, 40 and 60 h, respectively. For simplicity,the chemical composition of ball-milled alloys was defined as LaMg11Ni+xNi (x...J. Cent. South Univ.

. Effect of ball-milling duration and dehydrogenation on the morphology, microstructure and catalyst dispersion in Ni-catalyzed MgH2 hydrogen storage materials [J]. Acta Materialia, 2015, 86: 55-68...Trans. Nonferrous Met. Soc. China 27(2017) 569-577 Role of milling time and Ni content on dehydrogenation behavior of MgH2/Ni composite Li-shuai XIE, Jin-shan LI, Tie-bang ZHANG, Hong-chao KOU State......
of milling duration and Ni content on the microstructures and electrochemical hydrogen storage performances of the ball-milled alloys were methodically studied.The ball-milled alloys obtain the optimum... of these alloys.The discharge capacities show a significant upward trend with milling duration prolonging,but milling for a longer time more than 40 h induces a slight decrease in the discharge capacity......

Shortening the Duration of Heat Treatment in the Lower Bainitic Range H.Vetters1,J.Dong1,H.-W.Zoch1 (1.Foundation Institute for Materials Science, Bremen, Germany) 摘要:In many cases an isothermal... bainitic treatment in salt bath is that the duration of the treatment is much longer than that of the martensitic hardening and this causes higher costs. Therefore it would be desirable to be able......
