The experimental CrFeMoNbTaTiZr alloys were designed based on the extremely low bio-toxicity of the chemical elements. They are currently used as a basis for alloying of classical alloys used in medical device manufacturing. From this alloying system, were obtained in a Vacuum Arc Remelting (VAR) equipment six alloys: CrFeMoNbTaTi, CrFeMoNbTaZr, CrFeMoTaTiZr, CrFeTaNbTiZr, CrTaNbTiZrMo and FeTaNbTiZrMo. The microstructural analysis of the obtained alloys have been performed by optical and SEM microscopy. The microhardness tests show results in the range of 575-1337 HV0.2/10. In order to improve the mechanical properties heat treatment procedures have been applied.
