This study introduces a newly developed Ti-based amorphous alloy with enhanced corrosion resistance, tailored for harsh environments. By replacing Hf misch metal elements (Ce and La) in Ti 41.5 Zr 2.5 5 Cu 42.5 Ni 7.5 Si 1 , the new demonstrated superior glass forming abilities, including largest supercooled liquidus region (Δ T ) of 35.75 °C highest enthalpy change H 135.19 J/g. Furthermore, this exhibited exceptional 200 times minimized mass loss 10% HCl compared to its counterpart, significantly outperforming conventional crystalline other alloys. smaller powders (<25 μm), produced under higher cooling rates, retained their structure showed optimal performance, highlighting critical role particle size ensuring consistent properties. These results establish as promising material advanced applications requiring durability manufacturability.
