Effects of Pd substitution for Ni on corrosion performances of Mg0.9Ti0.1Ni1-xPdx hydrogen storage alloys TIAN Qi-feng(田琦峰)1,2, ZHANG Yao(张 耀)1,2, TAN Zhi-cheng(谭志诚)1,2, XU Fen(徐 芬) 1,2, SUN Li...: The Mg0.9Ti0.1Ni1-xPdx (x= 0, 0.05, 0.1, 0.15) hydrogen storage electrode alloys were prepared by mechanical alloying. The main phases of the alloys were determined as amorphous by X-ray diffraction(XRD......
, 423 K) and the results show that the maximum absorbed hydrogen capacity reaches 1.45% (5.79H/M) under a hydrogen pressure of 4.3 MPa at 373 K. The XRD patterns during absorbing procedure at 373 K... storage material. During the last years, magnesium based alloys showed large potential for hydrogen storage applications due to their high hydrogen capacity and low costs [1,2], but because of the high......

March 2014 Abstract: The effects of substitution of Sn for Co on the microstructure, hydrogen storage and electrochemical discharge capacity of La0.7Mg0.3Al0.3Mn0.4Co0.5-xSnxNi3.8 (x=0, 0.1, 0.2, 0.3.... The PCT showed that increasing substitution of Sn for Co results in decrease of the maximum hydrogen storage capacity from 1.48% (x=0) to 0.85% (x=0.5). The electrochemical tests indicated......

Finite element analysis of effect of soil displacement on bearing capacity of single friction pileWANG Li(王丽)1, ZHENG Gang(郑刚)2, OU Ruo-nan(欧若楠)3(1. School of Civil and Safety Engineering, Dalian...). Soil pressures along pile increase due to surcharge load and uniform soil movement, and so do the shaft resistances along pile, as a result, when rebars in concrete piles are enough, bearing capacity......
