Real time investigation of the grain refinement dynamics in zinc alloy by synchrotron microradiography

Effect of combined addition of Al-Ti-B ribbon and Zr element on the microstructure, mechanical and damping properties of ZA22 alloy

“…It is assumed that this should be related to the facilitating roles of finer TiB 2 and L12-Al 3 Ti particles on the heterogeneous nucleation of α-Al grains. This phenomenon was also reported by other researchers in their study on ZA27 alloy refined by TiB 2 particles [35]. From Fig.…”

“…Another reason for the enhancement of strength is mainly attributed to the dispersion strengthening effect of fine TiB 2 and L1 2 -Al 3 Ti particles, which act as strong impenetrable barriers to block the motions of dislocations under applied tensile load [35,40,41].…”

Dendrite growth in the recharging process of zinc–air batteries

“…[16][17][18][19] Chen et al proposed a nonlinear phase eld model for electrodeposition. [20][21][22][23] To facilitate the observation on the growth behavior of dendrites and morphological characteristics in the process of electrodeposition, some kinds of instruments can be employed such as scanning electron microscopes, [24][25][26] transmission electron microscopes, 27 optical microscopes, 28 and atomic force microscopes. 29 Some researchers have already conducted investigations on the mechanism of zinc dendrite growth.…”

Microstructure and Wear Behavior of In Situ ZA27/TiB2 Composites

“…When the TiB2 content increases from 0 to 3%, the average grain size of α-Al decreases from 205.4 to 52.3 μm. The corresponding grain refinement mechanisms have been revealed in our previous work [28]. The TiB2 particles distribute uniformly in the matrix, and there is no obvious particle aggregation.…”
