The crystal arrangement is face centred cubic (fcc ... For certain steels, the rapid cooling necessary to produce a martensitic structure (e.g. water or brine baths) introduces large surface tensile ...

Goodtzow (NATURE, 119, 494; 1927), that quenched carbon steels contain a phase with a tetragonal crystal structure ... present knowledge of the tetragonal martensite may be briefly summarised ...

The other way is to alter its crystal structure and makeup ... cycles have been developed to alter the structure of steel. For example, when martensite is tempered (heated below A3 temperature ...

Figure 1: Martensitic distortions of the B2 crystal structure of NiTi. Figure 2: Total energies and internal parameters with respect to monoclinic angle γ. The stability of the BCO structure can ...

The black grains are the martensitic phase and the white the non-transformed austenite. The transformation does not involve diffusion processes but lattice displacement of atoms by shear produced by ...

Martensite is a form of steel made by quenching ... These jumping crystals change their crystal structure when heated to between 65 and 67 °C; they return to their starting structure upon cooling ...

Martensite comprises of supersaturated carbon, distorting the crystal lattice away from body centered cubic ... clearly reveals the hierarchical nature of the martensitic structure, with the ...

The increased carbon content and chemical makeup of MSS forces the atoms into a distorted body-centered cubic or body-centered tetragonal martensitic crystal structure when the alloys are hardened.
