Study of samples and cross sections of wire which have been mounted and polished for examination under high power microscope

Microscopic examination of a metal's crystalline structure, used in conjunction with spectroscopy to determine the composition of a specimen's iron component and the methods by which it was refined ( smelted) into a workable metal. The metal's crystalline structure are examined, using the ferrite, pearlite, and martensite crystal structures and slag content. It can also determine the armount of carbon present in the metal and the method used to achieve heat treating.

The study of the crystalline structures of metals & alloys.

The science or art of metals and metal working; also, a treatise on metals.

A substitute for lithography, in which metallic plates are used instead of stone.

A method of transferring impressions of the grain of wood to metallic surfaces by chemical action.
