The role of titanium content in (Ni75Cr15Si10)100−xTix bulk metallic glass systems to elevate mechanical and corrosion properties.

Bulk metallic glass (BMG) samples are amalgamated by high-energy ball milling using the general formula (Ni75Cr15Si10)100−xTix (labelled as NCSTx, where x = 0,4, 8 and 12 at.%). The crystallinity and phase attribution properties of nickel (Ni), chromium (Cr), silicon (Si) and titanium (Ti) are scrutinized using the XRD analysis. The trend related to glass-forming ability (ΔT) and the GFA parameter (γ) is NCST8 > NCST12 > NCST4 > NCST0, which confirms that NCST8 sample shows superior glass-forming ability. The reduced glass transition temperature (Trg) for all the present BMG systems is greater than 0.5, which offers its good thermal stability and glass-forming ability (GFA). Corrosion studies suggested that a sample, having dynamic nature towards corrosion resistance and potential (Ec) (NCST8, (Ni75Cr15Si10)92Ti8), exhibits relatively lower values of both ic (4.7 × 10−4 A/cm2) and ip (0.0079 A/cm2), as recommended in potentio-dynamic findings.
