Abstract

The invention discloses a determination device and determination method for metal solid / liquid phase interface energy, and belongs to the technical field of design and manufacturing of metallurgical test determination equipment. The invention provides the determination device and the determination method for metal solid / liquid phase interface energy and capable of controlling the oxygen content of the environment on line. The determination device comprises an environmental simulation system, a heating system and a metal melt change process recording system; the environmental simulation system at least comprises a set of low-oxygen environment formation simulator; a metal sample arranged in the environmental simulation system is heated in the environmental simulation system by the heating system to be melted, and is recorded by the metal melt change process recording system. According to the determination method, the oxygen content of the environmental simulation system is adjusted by the low-oxygen environment formation simulator, recording is conducted by the metal melt change process recording system, the wetting angle of the interface condition under different oxygen content conditions is measured, and the interface tension is calculated by the surface tension.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for metal solid / liquid interface energy, and belongs to the technical field of metallurgical test measuring equipment design and manufacture. The present invention also relates to a method for measuring metal solid / liquid interface energy by using the measuring device Background technique [0002] In the production process of metal materials, there are often some non-metallic elements in the molten metal combined with alloying elements in the metal to form tiny particles. Some of these particles can promote metal solidification and refine metal solidification structure, and are called nucleating agents. According to the classical nucleation theory, the interfacial energy between the nucleating agent and the melt and the interfacial energy between the nucleating agent and the crystal nucleus are the key factors affecting the nucleation of anisotropic metals, which directly...
