The mechanical properties of lithium tetraborate (LTB) were studied using micro- and nanoindentation on (100), (011) and (112) oriented plates. The lowest values of the hardness obtained for the LTB (100) face are caused by relatively easy cleavage parallel to the {100} planes. The hardness values decrease at the maximal load increasing for the LTB faces studied, however the indentation size effect...
A systematic study of mechanical deformation of boron carbide under contact loading is conducted using scratching and depth-sensing indentation (nanoindentation). Both single crystal and polycrystalline materials are investigated by means of Raman microspectroscopy and transmission electron microscopy (TEM). High resolution TEM images of scratch debris reveal various microstructural changes including...
