Cu50Zr40Ti10 （at）的热、机械和腐蚀性能。%)金属玻璃也进行了研究。玻璃化转变温度Tg为624.4 K，结晶起始温度TX为691.1 K，过冷液区△TX为66.7 K。弹性应变、断裂强度和弹性模量分别为2.13%、2099.78 MPa和86.85 GPa。在1 M HCl、1 M NaCl和0.5 M H2SO4溶液中，在298 K的空气中，腐蚀速率分别为0.4759、0.1076和1.758×10-3 mm/年。在HCl和NaCl中可以观察到钝化膜，但在H2SO4中没有，前者的腐蚀产物比后者的腐蚀产物更疏松，导致后者的耐蚀性优于前者。
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.
