Amorphous matter is not only a large class of condensed matter, but also an important part of contemporary material physics, and has important theoretical research value and a wide range of applications. In order to clarify the physical essence of amorphous matter, the project intends to study systematically thermal properties of typical amorphous system, metallic glass forming system. Experimental measurement and numerical analysis are used to obtain the evolution law and basic behavior characteristics of the specific heat, entropy and enthalpy of the glass forming system; molecular dynamics simulation will give in details the characteristics of the thermal properties of glass, supercooled liquid and normal liquid, and the intrinsic connections between the thermal properties and structure, interaction and the elemental unit movement. Combining experiment with theory, we further clarify the intrinsic mechanism of thermal properties, and realize the theoretical modeling of the typical glass forming system, then establish the correlation between dynamics and thermodynamics. The implementation of this project will help further understand the glass transition and the nature of glass, which are long-standing issues in science, and provide strong support in theory for the development and application of amorphous materials.
