  Mechanical amorphization, a widely observed phenomenon, has been utilized to
synthesize novel phases by inducing disorder through external loading, thereby
expanding the realm of glass-forming systems. Empirically, it has been
plausible that mechanical amorphization ability consistently correlates with
glass-forming ability. However, through a comprehensive investigation in
binary, ternary, and quaternary systems combining neutron diffraction,
calorimetric experimental approaches and molecular dynamics simulation, we
demonstrate that this impression is only partly true and we reveal that the
mechanical amorphization ability can be inversely correlated with the glass
forming ability in certain cases To provide insights into these intriguing
findings, we present a stress-dependent nucleation theory that offers a
coherent explanation for both experimental and simulation results. Our study
identifies the intensity of mechanical work, contributed by external stress, as
the key control parameter for mechanical amorphization, rendering the ability
to tune this process. This discovery not only unravels the underlying
correlation between mechanical amorphization and glass-forming ability but also
provides a pathway for the design and discovery of new amorphous phases with
tailored properties.
