Microhardness, fracture mechanism and dielectric behaviour of flux-grown GdFeO3 single crystals

Experimental nanoindentation of BCC metals

The load dependence of the Vickers microhardness of SrLaAlO4 and SrLaGaO4 single crystals, using a PMT-3 hardness tester, has been investigated and analysed from the standpoint of various theoretical models. On the (100) and (001) planes of these crystals, reverse indentation size effect was observed. Analysis of the experimental data revealed: (1) the indentation size effect is best described by Meyer's law and the proportional specimen resistance model of Li and Bradt, (2) indentation-induced cracking model for reverse indentation size effect and Meyer's law cannot be used to determine the hardness of the crystals, (3) as shown by the negative values of the load-dependent quantities in Hays-Kendall's approach and Li-Bradt model, the origin of indentation size effect is associated with the processes of relaxation of indentation stresses, and (4) the load-dependent and load-independent quantities of different models are interrelated and are intimately connected with the orientation and chemical composition of the crystals. It was also found that the plots of the ratio of indentation load to indentation diagonal against indentation diagonal for a sample exhibit two different slopes with a transition in the slopes occurring at an indentation diagonal, whose value depends on the indenter orientation, indented plane and chemical composition of the crystals. The physical significance of the appearance of these transitions and the nature of load-independent indentation microhardness are discussed.

Study of indentation size effect and microhardness of SrLaAlO4 and SrLaGaO4 single crystals

The mechanical behaviour of BaFCI single crystals has been investigated by use of Vickers microindentation. The tests performed on (0 0 1) and (1 0 0) planes show an important hardness anisotropy, higher values being obtained on (1 0 0) planes and all being close to that of BaF2. A qualitative investigation of the impressions has established the occurrence of cleavage along {1 0 0} planes, whereas slip occurs much more easily along (0 0 1) planes. For tests performed on the (0 0 1) plane, a quantitative analysis of the indentation cracks yields a very low toughness value. On comparing the BaFCl and BaF2 structures, it is concluded that the chlorine layers introduce a marked anisotropy but do not have the expected weakening effect.
