热处理材料晶体结构的相变研究

THE TRANSITION RESEARCH OF HEAT TREATMENT MATERIAL CRYSTAL STRUCTURE

金属材料经过热处理过程使材料具有优良的组织和性能，广泛应用于先进科技和日常生活中。金属材料的微观显微组织是研究金属材料组织性能的有效方法。金属材料微观组织的形成是金属材料合金成分在金属晶体晶胞中的溶入析出，金属晶体的晶格结构从体心立方晶格转变成面心立方晶格和密排六方晶格。金属材料不同的热处理过冷转变温度形成不同的微观形态的相结构。金属材料从加热状态冷却到室温，金属材料微观晶格结构的变化我们称之为相变。

metal materials after heat treatment process so that the materials have excellent microstructure and properties widely used in advanced technology and dail life. Metal mate rials microsttucture analysis a effective method to study of metallic materials structure and properties. Metal materials microstructure formation is a procedure of alloy compositions in metal crystal lattice dissolution and procipitation, metal crystal lattice strucrure from a body-centered cublc lattice into dense row of six cubic lattice and face centered cubic lattice. Metallic materials of different heat treatment ocld transformation tempreture form different microscopic porphology of the phase structure. From the high temperature heating to colling room temperature. the metal materials microscopic lattice structure changes we called phase transition. This paper we study of metallic materials the microscopic crstal structure of phase transition proces.
