Figure 4

SEM images of Al0.3NbTa0.8Ti1.5V0.2Zr powders after different milling times from 20 to 50 h, respectively. The milling times are shown on the left side of each row of images. (a,d,g,j) SEM micrographs using SE detector showing powders in detail after each milling from 20 to 50 h, in order. (b,e,h,k) Corresponding SEM images using BSE detector showing powders in detail after each milling. (c,f,i,l) SEM images using BSE mode to exhibit an overview of the powders in lower magnifications. (1–4) EDS maps taken from the particle cross-section of each powder milled from 20 to 50 h, respectively.
