An electron probe X-ray microanalyzer (EPMA) is an essential tool for studying chemical composition distribution in the microstructure. Quantifying chemical composition using standard specimens is commonly used to determine the composition of individual phases. However, the local difference in chemical composition in the standard specimens brings t...
In dynamic theory, one of the possible variants of the formation of martensite crystals upon the reverse α–γ transformation in Fe–Ni alloys connected with the participation of the intermediate e phase is discussed. The mechanism of planar tension–compression deformation of {110}
Different variants of the formation of martensite crystals upon the α–γ transformation caused by the tension–compression deformation of {110}α planes have been considered according to the dynamic theory of martensitic transformations. In contrast to previous works, here we take into account the deviation (angle θ) of the principal directions of def...
In this work, we have considered different variants of the formation of martensite crystals upon the α–ε transformation caused by the deformation of planes {112}α that leads to the symmetry of atomic arrangement typical of the basal planes {0001} ε of the ε phase within the dynamic theory of martensitic transformations. It has been shown that there...
An isothermal transformation was observed when a fully austenitized lean-alloyed, low C steel was quenched to a temperature in the M (S) to M (f) temperature range and held at the quenching temperature. The dilatometric analysis revealed that the isothermal transformation was distinct from the bainitic transformation. Internal friction (IF) measure...
