Web27 okt. 2024 · In general, a unit cell is defined by the lengths of three axes ( a, b, and c) and the angles ( α, β, and γ) between them, as illustrated in Figure \PageIndex {10}. The axes are defined as being the lengths between points in the space lattice. Consequently, unit cell axes join points with identical environments. Web6 jul. 2024 · Iron materials below 2.06 % carbon consist of a eutectoid based microstructure ( pearlite) and above 2.06 % of a eutectic based microstructure (ledeburite). In principle, this also results in other material properties. This difference is also reflected in the subdivision into steels and cast iron.
