The Influence of the Third Element on Nano-Mechanical Properties of Iron Borides FeB and FeB Formed in Fe-B-X (X = C, Cr, Mn, V, W, Mn + V) Alloys.

In this study, the influence of alloying elements on the mechanical properties of iron borides FeB and FeB formed in Fe-B-X (X = C, Cr, Mn, V, W, Mn + V) alloys were evaluated using instrumented indentation measurement. The microstructural characterization of the alloys was performed by means of X-ray diffraction and scanning electron microscope equipped with an energy dispersive X-ray analyzer. The fraction of the phases present in the alloys was determined either by the lever rule or by image analysis.
