Indentation-induced twinning in LaAlO3 single crystals: An atomic force microscopy study

Distinguishing between slip and twinning events during nanoindentation of magnesium alloy AZ31

“…The characterization of the deformation around the indentation imprint was carried out using atomic force microscopy (AFM) in the PeakForce error mode available with Bruker Multimode 8 equipment. This enables identification of slip lines and twins [6,21,22]. Over 300 indents on 22 grains were examined.…”

The effect of cooling rates on the refinement of microstructure and the nanoscale indentation creep behavior of Mg–Al–Ca alloy

“…Additionally, twinning can be induced during indentation deformation below the indent [44][45][46][47]. Giuliani et al [44] used a focused ion beam to produce cross-sectional TEM samples to analyze the deformation under the indents, and it was found that the predominant mechanism of deformation below the indent is twinning at room temperature.…”

“…Giuliani et al [44] used a focused ion beam to produce cross-sectional TEM samples to analyze the deformation under the indents, and it was found that the predominant mechanism of deformation below the indent is twinning at room temperature. Tall et al [45] reported that plasticity occurs at room temperature through the nucleation of mechanical twins which may result from elastic relaxation of the twinning dislocations when the residual stress is relaxed. Hsiung et al [46] suggested that deformation twinning starts to involve in creep deformation when the alloy is creep deformed at a high stress level.…”

Hydrothermal synthesis and characterization of polycrystalline gadolinium aluminum perovskite (GdAlO3, GAP)

“…Related ceramic perovskite materials are currently being incorporated into automobile catalytic converters; they are also promising substrates for the epitaxy of thin oxide films having potential use as buffer layers for the epitaxial growth of various perovskite-type films, such as high temperature superconductors, ferroelectrics, piezoelectric and colossal magnetoresistance oxides. Some perovskites also exhibit very large values of electric permittivity [2,[11][12][13][14][15].…”
