(4): 310-316. DOI: 10.1007/s40830-016-0083-y. [21] ZHAO Chun-yang, LIANG Hai-long, LUO Shun-cun, YANG Jing-jing, WANG Ze-min. The effect of energy input on reaction, phase transition and shape memory......
current density is almost identical for alloys with W phase, but the cathodic current density increases as the Y content and amount of the W phase in the alloy increase. The cathodic reaction became.... [42] LIU J F, YANG Z Q, YE H Q. In situ transmission electron microscopy investigation of quasicrystal-crystal transformations in Mg–Zn–Y alloys [J]. Journal of Alloys and Compounds, 2015, 621: 179......
can be obtained by carrying out differentiation of the TG curve, which can be used to record the speed of mass loss with temperature, to determine the maximum reaction speed, and to divide the free......
