Computer Programs

MAP_STEEL_TEXTURE PROGRAM: Calculation of the crystallographic texture obtained when austenite transforms into martensite. The austenite itself can be textured.
MAP_STEEL_TEXTURE2 PROGRAM:To produce a non-random, crystallographically textured distribution of austenite grains.
MAP_STEEL_TEXTURE3 PROGRAM:Calculation of habit plane, shape deformation and orientation relationship between austenite and martensite or bainite, as a function of the correspondence matrix and the lattice invariant deformation.
MAP_STEEL_DIFFRACT_FERRITE PROGRAM:Calculation of Debye X-ray diffraction rings due to stress-induced transformation of polycrystalline austenite. The sample may be textured.
MAP_STEEL_DIFFRACT_AUSTENITE PROGRAM:Calculation of Debye X-ray diffraction rings for polycrystalline austenite. The sample may be textured.
MAP_STEEL_TRANS_PLASTICITY PROGRAM:Calculation of transformation strain and crystallographic orientation of the 24 variants of martensite or bainite that form in a singel grain of austenite in an arbitrary orientation.
MAP_STEEL_TWIP PROGRAM:A program for the calculation of texture change due to twinning and true strain from twinning, as a function of twinning volume fraction, texture type and its intensity.
MAP_STEEL_FERRITE_TEXTURE PROGRAM:Calculates probability of an allotriomorph of ferrite which nucleates at an austenite grain boundary having a good-fit orientation relationship with both of the adjacent austenite grain, and the resulting crystallographic texture.
