Nanoindentation Analysis of Inconel 625 Alloy Weld Overlay on 16Mo3 Steel

This article deals with nanoindentation analysis of welded overlay layer Inconel 625 alloy on 16Mo3 steel and their interface (transition zone). The microstructure weld metal is analyzed, as well the weld-on subsequently properties (nanohardnes, reduced modulus elastic-ity) selected structural components. realized a tube made steel, which bent by so-called critical bending (d≤0,7D). also change investigated after that bending. samples prepared from areas highest compressive tensile load outer, respectively inner bend arc were used for research. Nanoindentation was performed using Hysitron Triboin-denter TI950 its evaluation software Triboscan.
