Abstract

By combining neutron diffraction, high-resolution transmission electron microscopy and thermal analysis measurements, the microstructure of as-cast Ti₄₀Zr₂₅Ni₈Cu₉Be₁₈ BMG with diameter of 2 mm was identified to be quenched-in nuclei/amorphous matrix. The quenched-in nuclei transform to (Ti,Zr)Be₂ nanocrystals with the average size of 4 nm homogeneously distributed into the amorphous matrix during deformation, which could be responsible for the large room-temperature compressive plastic strain, up to 8.0% at a constant strain rate of 5 × 10^-4 s^-1.
