However, if light or electrons pass through a round hole or an aperture, the trajectories no longer converge to a single point but are slightly enlarged as concentric rings with a very intense circle at the center, as shown in Fig. 2...

...). It corresponds to a low Miller index plane. For example, (111) and (100) surfaces of face-centered cubic (fcc) crystals and the (110) surface of body-centered cubic crystals are singular. Most surfaces are body-centered cubic (bcc); that is, some atoms in deeper layers also have broken nearest-neighbor bonds...

... are body-centered cubic (bcc). The high-temperature β phase is disordered, while the lower-temperature β′ phase is ordered ( Fig. 4 ) These alloys are easy to machine and hot form but are not very amendable to cold forming, because the β′ phase is brittle at room temperature. There is also a rapid...
