Machining methods like drilling to make holes or milling are examples of other common deformation processing methods. Hot Rolling process at Inland Steel Corporation. This is key to the question of characterizing the material and to form a basis for understanding the state or condition of the material. These arrangements are correlated with the processing and coupled strongly with the material properties. Understanding these levels of the structure of materials is a basic part of the role of a materials person and this structural information serves as a means to understand and control the processing stages and to provide a similar basis for the physical properties of the material.
Structural information comes in a series of size scales.
The physical properties of the material are generally a basic reason for selecting the material for the needed product performance. The performance of a product frequently requires various behaviors and thus types of properties. It is frequently found that a compromise among the needed properties must be made to be consistent with the processing selected and the structural state desired or possible. Most of the useful properties are related to the structural state of the material. Tensile strength, fracture toughness, fatigue strength, creep strength, hardness, etc.
