一、相图研究的意义 相图是对一个物质体系相平衡进行图示的总称。它描述的是一个体系当相平衡时在给定状态条件下另一些热力学变量的变化轨迹,所提供的相平衡信息对人们研究物质世界具有重要意义。当今相图的广义概念,包括了物质相的热力学性质和相平衡研究的整个内容。相图研究的物质对象涉及各个工业和技术领域。在材料科学中,它是选择材料成分、制定处理工艺
First, the meaning of phase diagram research phase diagram is a general term for the physical balance of a material system. It describes the trajectories of other thermodynamic variables in a given system under phase equilibrium. The phase equilibrium information provided is of great importance for people to study the physical world. The broad concept of phase diagrams today includes the entire thermodynamic nature of the phase and the phase equilibrium study. The material objects of the phase diagram study cover various industrial and technical fields. In materials science, it is the choice of material composition, the development of processing technology
