Age hardening characteristics and mechanical properties of Mg-3.5Dy-4.0Gd-3.1Nd-0.4Zr alloy LI De-hui(李德辉)1, DONG Jie(董 杰)1, ZENG Xiao-qin(曾小勤)1, LU Chen(卢 晨)1, DING Wen-jiang(丁文江)1 National Engineering Research Center for Light Alloy Net Forming, Shanghai Jiao Tong University, Shanghai 200030, China Received 28 July 2006; accepted 15 September 2006 Abstract: Age hardening characteristic......
Electocbemical Process of Ti-Ni Alloy Electrodes by Cyclic Voltammetry赵建民,李国勋摘 要:<正> The electrochemical process of Ti-Ni alloy electrode was studied by using cyclic voltammetry. Thehydrogen-absorbing electrode could be approximately regarded as a reversible hydrogen elecrede. The con-trolling steps of the discharging process varying......
potential (OCP), cyclic polarization and electrochemical impedance spectra (EIS) of the Al alloys were measured after treatment in three solutions (3.5% NaCl (mass fraction); 10 mmol/L NaCl + 0.1 mol/L... for the 7150 Al alloy with T76 + T6 treatment. Key words: 7150 aluminum alloy; novel three-step aging; cyclic polarization; electrochemical impedance spectroscopy  ......
are described. In the next section there is a comparison between manual operation of hardening machines vs. automated lines. Since there are applications for each, manual and fully automated hardening systems, HEESS has not only focused to develop automated lines, but also refined manual operated hardening machines (SP-Series). These take advantage of the latest technology, like for example quick tool......
