Industrial pure iron samples were austenitized and quenched (6°C/s cooling to room temperature) under hydrostatic pressure of 3–5 GPa. The morphology, phase transformation strengthening mechanism high-pressure martensite are analyzed by the method SEM, XRD, EBSD, TEM. Lath with hierarchical packet-block-lath structure is induced in industrial high pressure, which keeps Kurdjumov-Sachs (K-S) ori...

LLE Review, Volume 66 103 Low-Molar-Mass Liquid Crystals Liquid crystals (LC’s) represent a state-of-matter intermediate between a solid crystal and an isotropic liquid. A liquid crystal flows like an ordinary liquid, while other properties, such as optical and dielectric anisotropies, resemble those of a crystalline solid.1 In general, a somewhat rigid and anisomeric molecular shape (e.g., cyl...

The toughness of martensitic steels is strongly related to their fine and complex morphologies. To control the steels, effect carbon content on morphology lath martensite must be studied. However, these morphological changes are difficult clarify using conventional two-dimensional observations because morphologies tangled. Previously, we analysed reported three-dimensional microstructures ultra...

Martensite/ferrite (M/F) interface damage plays a critical role in controlling failure of dual-phase (DP) steels and is commonly understood to originate from the large phase contrast between martensite ferrite. This however conflicts with few, recent observations, showing that considerable M/F initiation often accompanied by apparent island plasticity weak strain partitioning. In fact, has comp...
