Figure 2

EDS elemental maps show the distribution of Mg (red dots) in the titanium matrix processed at rotational speeds of (a) 1250 rpm, (b) 800 rpm, and (c) 1600 rpm. The dwell time was 15 s. (d) XRD pattern indicates the formation of Mg islands inside the titanium matrix after FSI at 1250 rpm for 15 s. (e) XRD pattern determines that after chemical etching, Mg was etched out while characteristic peaks of MgH2 are still visible.
