摘　　要：金相学是用显微镜研究金属的物理结构和成分。金相样品的表面是通过各种研磨、抛光和蚀刻的方法来制备的。在制备后,通常使用光学显微镜或电子显微镜进行分析。在本文中,重点介绍了利用光镜表征高温钛合金IMI834,观察其不同微观组织所表现出的不同形貌特征。Metallography is the use of a microscope to study the physical structure and composition of metals.The surface of the metallographic sample is prepared by various grinding,polishing and etching methods.After preparation,an optical microscope or an electron microscope is usually used for analysis.In this article,the focus is on the use of light microscope to characterize the high-temperature titanium alloy IMI834,and to observe the different morphological characteristics of different microstructures.

关 键 词：金相学 高温钛合金IMI834 微观组织 形貌特征
