What is metallography?

Metallography [jρnxiàng] says that water is better than fire. Metaphor is a perfect form. Refers to the gilded statue of Buddha and Bodhisattva.

Metallography refers to the internal structure of metal or alloy, that is, the chemical composition of metal or alloy and the physical and chemical state of various components in alloy.

Metallographic structure reflects the specific morphology of metal metallography, such as martensite, austenite, ferrite, pearlite and so on. Metallographic structure in a broad sense refers to the mixed state and interaction state of two or more substances in a microscopic state.
