FCC, BCC, and HCP Crystal Structures: A Visual Guide |

Описание: FCC, BCC, and HCP are the three most common crystal structures found in nature. They are responsible for the many different properties of materials, such as strength, hardness, and ductility. #BME210 #EME230

In this video, we will take a visual look at these three crystal structures. We will see how the atoms are arranged differently in each structure, and how this affects their properties.

FCC stands for face-centered cubic. In an FCC crystal structure, the atoms are arranged at the corners of a cube and at the centers of each face. This gives the structure a high coordination number, which means that each atom is surrounded by many other atoms. This makes FCC materials very strong and ductile.

BCC stands for body-centered cubic. In a BCC crystal structure, the atoms are arranged at the corners of a cube and at the center of the cube. This gives the structure a lower coordination number than FCC, which makes BCC materials less strong and ductile. However, BCC materials are more ductile than HCP materials.

HCP stands for hexagonal close-packed. In an HCP crystal structure, the atoms are arranged in a layered fashion. This gives the structure a high packing density, which means that there is very little empty space between the atoms. This makes HCP materials very hard and brittle.
