Structure, thermal and corrosion behavior of (Ti41Zr25Be28Fe6)93Cu7 bulk metallic glass in two different solutions were studied using X-ray diffraction pattern, Vickers micro hardness test, Differential Scaning Calorimetry and tafel polarization methods. The amorphous samples were heated up to the final temperature of crystallization. It was revealed that the studied alloy has complex crystallization behavior including 5 steps of crystallization. Crystallized phases of each crystallization step and its hardness were identified. The studied alloy with corrosion current density of 0.4 μA/cm2 in 3.5wt % NaCl solution is a suitable candidate for engineering and biomedical applications. Heating the samples in super cooled region showed insignificant changes in corrosion rate. An obvious decrease in corrosion resistance was observed in samples heated in crystallization region.
