金相学是一门使用显微镜研究金属及合金内部组织的学科。广义的金相学与金属学相似。金相学主要研究的是金属及合金因化学成分、冷凝、压延、焊接、热处理等所引起的内部组织改变及其对物理、化学和力学性能的影响。随着新材料的不断出现,目前金相学的研究范围已经不仅限于金属与合金。金相学的研究对材料评价和故障分析有重要的意义。

In some cases, the metallographic structure is large enough to be seen with the unaided eye.
Hot mounting: The specimens are placed in the mounting press, and the resin is added. The specimens are mounted under heat and high pressure.
Cold mounting: The specimens are placed in a mounting cup and mounting material is then poured over the specimens. A vacuum impregnation unit (photo) is used for mounting of porous materials.

Metallography is the study of the physical structure and components of metals, typically using microscopy.

Ceramic and polymeric materials may also be prepared using metallographic techniques, hence the terms ceramography, plastography and, collectively, materialography.
