Abstract
In this work, a new series of Co71-xNixMo9P14B6 (x = 15, 20, 30 at.%) Bulk metallic glasses (BMGs) with the critical diameter of 2.0 mm were synthesized by fluxing treatment and J-quenching technique. The glass forming ability (GFA), corrosion properties, mechanical and magnetic properties of the present Co-based bulk metallic glasses (BMGs) have been studied systematically. The corrosion tests show that the corrosion current density in 3.5% NaCl and 1 M HCl solutions up to the order of 10−7A/cm2. The compressive tests show that the present Co-based BMGs exhibit a compressive fracture strength of 2.7 – 3.2 GPa, the maximum compressive plastic strain of 2.3%. The present Co-based BMGs have extremely value of the low saturated magnetizations (Bs), exhibiting great potential for industry applications
