Mechanisms and Characteristics of Thermodynamically Quasistable Structure Formation in Metals

Abstract This paper investigates the processes of thermodynamic pseudostability (metastability) in liquid metals during rapid solidification, a mechanism that results in the formation of an amorphous structure. Established technologies for creating bulk amorphous materials are typically limited to producing only a thin amorphous layer. This limitation stems from the thermal inertia of the materials, which inherently tend towards thermodynamic equilibrium. In the present study, a novel approach is proposed to intensify heat exchange by utilizing inoculants within the liquid melts combined with high-velocity cooling. To facilitate process prediction and optimization, a mathematical model of the massive amorphous layer formation process is introduced. This model allows for the accurate prediction of the amorphization process evolution and subsequent optimization of the critical technological parameters.
