WebThe body-centered cubic (bcc) lattice ( Figure 1.4b) can be obtained by adding a second lattice point at the center of each cubic cell of a simple cubic lattice. Thus, the unit cell of … WebBody Centred Cubic and Face Centred Cubic BCC – Body Centred Cubic – and FCC – Face Centred Cubic – are descriptions of the arrangement of atoms in crystal structures. Most metal and alloys are crystalline, which means that their atoms arrange themselves in an ordered pattern.
WebThe new alloy transformed from the BCC to hexagonal closed-packed (HCP) phase initially. With increasing load the HCP phase was gradually converted into face-centred cubic (FCC); the resultant HCP/FCC nanolaminates enhanced plasticity via strain partitioning. Under higher loads, the FCC phase became dominant, giving rise to deformation twinning. WebApr 10, 2024 · This work shows that by designing appropriate alloying elements in a body-centred-cubic high-entropy alloy, local chemical order and lattice distortion can be tuned, which influences the evolution ...
