To INFJs, the world is a place full of inequity â but it doesnât have to be. No other personality type is better suited to create a movement to right a wrong, no matter how big or small. INFJs just need to remember that while theyâre busy taking care of the world, they need to take care of themselves, too.
Solid copper can be described as the arrangement of copper atoms in a face-centered-cubic (fcc) configuration. A copper atom is found at each corner and in the center of each face of a cube as depicted in Figure 1. This is the unit cell which is repeated in three dimensional space to make up the crystal structure of the metal. The atoms are held in place in the structure by the energy of the atomic attractions between them.
As designers, we ideally want the DBTT to be as low as possible for low-temperature design. Metals such as aluminum, gold, silver, and copper have an FCC (face-centred cubic) crystal lattice structure, and most do not experience a shift from ductile to brittle behaviour. Other metals, such as iron, many steels, chromium, and tungsten, have a BCC (body-centred cubic) crystal structure and experience a sharp, often non-linear shift in ductility. Note that austenitic stainless steels, such as SAE 200- and 300-series (e.g. 316 stainless), have an FCC structure and do not experience a ductile-brittle transition.
