A face-centered cubic crystal structure will exhibit more ductility (deform more readily under load before breaking) than a body-centered cubic structure.
The bcc lattice, although cubic, is not closely packed and forms strong metals. Alpha-iron and tungsten have the bcc form.
Nimonic contains __________ percentage of nickel as that of Inconel.
Unlike steel alloys, brass cannot be hardened by heating.
Brass can only be strain or work-hardened.
The hardening occurs when the material is worked mechanically, e.g. by cold working.
The action of force does not harden brass
Sulfur is normally regarded as an impurity and has an adverse effect on impact properties when a steel is high in sulphur and low in manganese.
Sulphur improves machinability but lowers transverse ductility and notched impact toughness and has little effects on the longitudinal mechanical properties.
The ultimate tensile strength of low carbon steel by working at a high strain rate will
Depending on the temperature and composition of the steel, it can be hardened or softened.
To make steel harder, it must be heated to very high temperatures.
The final result of exactly how hard the steel becomes depends on the amount of carbon present in the metal.
The coordination number of a face centered cubic space lattice is
The face-centered cubic (fcc) has a coordination number of 12 and contains 4 atoms per unit cell.
The body-centered cubic (bcc) has a coordination number of 8 and contains 2 atoms per unit cell.
The simple cubic has a coordination number of 6 and contains 1 atom per unit cell
