Nanoindentation testing of low-alloyed molybdenum single crystals.
Original language description
The indentation hardness, Young´s modulus, total and plastic work of pure and low-alloyed molybdenum single crystals were investigated. It was found that the hardness of specimens decreases as the indentation load or indentation depth increases due to the indentation size effect (ISE). The same trend was observed for the EIT values of all specimens. The hardness estimated by the O-P method was significantly (up to 30 %) lower than the hardness determined using the total work-of-indentation approach. AFM3D-images of indentations showed that pile-up formation occurred at the edges of the indentations only in Mo-2 wt.% Nb single crystals with crystallographic orientation <100>. It was confirmed that nano-scale mechanical properties depend on the crystallographic orientations of single crystals. The alloying of molybdenum with niobium led to increasing of values of hardness and EIT.
