The results show that when Tm content increases to 3at%, the glass forming ability (GFA) and compressive plasticity are significantly improved, whereas GFA is decreased by adding excessive Tm. The maximum supercooled liquid region width (ΔTx) of the alloy with x=3 is 100 K, the compressive fracture strength is 1669 MPa, and the plastic strain is 21.01%, which are much higher than those of the Zr0.6336Cu0.1452Ni0.1012Al0.12 BMG (67 K, 1439 MPa, and 5.90%). However, the electrochemical test results show that the alloy with x=3 does not have excellent corrosion resistance in 3.5wt% NaCl solution, and the change trend of corrosion resistance and mechanical properties with Tm content is different from the expectation. The possible reason is that the excessive addition of rare-earth element Tm easily causes more oxides, which leads to the severe pitting corrosion. Further addition of Tm can improve the integrity and pitting corrosion resistance of Zr-based BMG passivation film, but the mechanical properties are not ideal."/>
