Using "3D-pinpointing approach",Zr_(55)Ti_2Co_(28)AI_(15) alloy with high glass-forming ability (GFA) is discovered in quaternary Zr-Ti-Co-AI system,whose critical diameter for BMG formation reaches 8 mm.In comparison with Ti-free ternary Zr_(56)Co_(28)Al_(16) BMG,glass transition temperature(T_9) of Zr_(55)Ti_2Co_(28)AI_(15) BMG decreases by about 9K.Nevertheless,no significant difference is observed in the elastic constants such as Young's modulus,shear modulus,bulk modulus and Poisson's… CONTINUE READING
