) and differential scanning calorimetry (DSC) were employed to investigate the influence of Ni content on the crystallization of amorphous Zr70,Cu30-xNi, (atom fraction in %) alloys. Experimental results show that with the Ni content increasing the activation energies for crystallization of amorphous Zr70Cu30-xNix alloys increase correspondingly, indicating that the thermal stability is greatly improved. All......

Properties of Fe-20Cr-4Al-Y Alloys李碚,孟广思,吴双霞,于洪香,金世生,杨保民摘 要:<正> 1. Introduction Light rare earth addition can remarkablyenhance the service life of Fe-Cr-Al alloyfor electrical heating element, but itscontent in the alloy must be controlledbelow the level of 0.1 wt-%. When thecontent exceeds that, the performance关键词:......
, rested for 15min and then discharged at 60 mA/g to the cut-off potential of -0.6 V. 3 Results and discussion 3.1 Electrochemical properties of alloys The electrochemical properties of the alloys... performance of alloys straightly relates to stoichiometric ratio. Since discharge voltage platform performance directly determines the continuance of 1.2 V discharge voltage plateau of Ni/MH battery......
