人类历史上曾有过以金属命名的青铜时代和铁器时代。科技史表明,人类对相交现象的观察也滥觞于古代(我国古籍中就有这方面的翔实记载),但发展成科学的理论,还是近代的事情。本世纪以来,其进展甚为可观;即以近十多年为例,相变理论及其应用在国内外均取得了若干引人注目的成果。例如,关于相界面和界面迁移、沉淀长大动力学和沉淀相的稳定性、Spinodal分解、热弹性马氏体相变和形状记忆效应、予马氏体现象和贝氏体长大机制等理论研究以及基于相变理论发展起
In the history of mankind, there were the Bronze Age and Iron Age which were named after the metal. The history of science and technology shows that human beings observe the phenomenon of intersection also appeared in ancient times (ancient Chinese books have detailed records in this respect), but the development into a scientific theory is still a modern one. Since the beginning of this century, its progress has been impressive. In recent decades, for example, the theory of phase transition and its applications have yielded some remarkable achievements both at home and abroad. For example, with regard to phase interface and interface migration, the theory of precipitation kinetics and stability of precipitated phases, Spinodal decomposition, thermoelastic martensitic transformation and shape memory effect, pre-martensite phenomena and bainite growth mechanism Research and development based on the theory of phase transition
