Cubic body centered
WebApr 10, 2024 · Body-centered cubic (BCC) multi-principal element alloys (MPEAs) have intrinsic high strength but poor ductility, which greatly limits their potential applications. WebAug 27, 2024 · A body-centered cubic (bcc) unit cell contains one additional component in the center of the cube. A face-centered cubic (fcc) unit cell contains a component in the center of each face in addition to those at the corners of the cube. Simple cubic and bcc arrangements fill only 52% and 68% of the available space with atoms, respectively.
