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 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 ...

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

But why did they find filigree austenite structures in the interior of individual martensite crystal grains? “When we saw that the manganese accumulated in thin tubes, we had the idea there could be ...
