The thermal, mechanical, and corrosive properties for Cu50Zr40Ti10 (at. %) metallic glass were also investigated. The glass transition temperature Tg, onset crystallization temperature TX, and under-cooled liquid region △TX are 624.4, 691.1, and 66.7 K, respectively. The elastic strain, fracture strength, and elastic modulus are 2.13 %, 2099.78 MPa, and 86.85 GPa, respectively. The corrosion rates in 1 M HCl, 1 M NaCl, and 0.5 M H2SO4 solutions open to air at 298 K are estimated to be about 0.4759, 0.1076, and 1.758×10-3 mm/year, respectively. The passive films can be observed in HCl and NaCl but not in H2SO4, the corrosion products in the former are looser than those in the latter, resulting in the better corrosion resistance in the latter than in the former.
