| Term | Definition |
| Herringbone Streaks | Elongated alternate bright and dull markings at an angle to the rolling direction and having the appearance of a herringbone pattern. |
| Homogenizing | A high temperature soaking treatment to eliminate or reduce segregation by diffusion. |
| Hot Working | Plastic deformation of metal at such temperature and rate that strain hardening does not occur. |
| Impact | A part formed in a press from a metal slug in a die, usually cold, by rapid application of force through a punch, causing the metal to flow around the punch and/or through an opening in the die. |
| Inclusion | Foreign material in the metal or impressed into the surface. |
| Intergranular Corrosion | Corrosion occuring preferentially at grain boundaries. |
| Interleaving | The insertion of paper between layers of metal to protect from damage or to facilitate shearing and prevent sticking of sheets of foil. |
| Kink | An abrupt bend or departure from flatness. |
| Lüders Lines | Surface markings resulting from localized flow which appear on some alloys after light straining. They lie approximately parallel to the direction of maximum shear stress (about 45 degrees to the direction of the applied stress), and appear as depressions when forming is in tension and as elevations when in compression. |
| Lateral Bow | Deviation of a longitudinal edge from straight (sometimes called camber). |
| Longitudinal Bow | A longitudinal curvature in the plane of a sheet. |
| Mean Diameter | The average of two measurements of the diameter taken at right angles to each other. |
| Mean Wall Thickness | The average of two measurements of the wall thickness of a tubular product, taken opposite each other. |
| Mechanical Properties | Those properties of a material that are associated with elastic and inelastic reaction when force is applied, or that involve the relationship between stress and strain; for example, modulus of elasticity, tensile strength, endurance limit. These properties are often referred to as "physical" properties. |
| MIL | A prefix for the US military's material specifications |
| Modulus of Elasticity | The ratio of stress to corresponding strain throughout the range where they are proportional. As there are three kinds of stresses, so there are three kinds of moduli of elasticity for any material-modulus in tension, in compression, and in shear.
|
| Modulus of Rigidity | The ratio of the unit shear stress in a torsion test, to the displacement caused by it per unit length in the elastic range. This modulus corresponds to the modulus of elasticity in the tension test. |
| Nick | A surface or edge discontinuity in the form of a slight cut, indentation, or notch. |
| Nickel | Nickel is a metallic chemical element in the periodic table that has the symbol Ni and atomic number 28. Nickel is pre-eminently an alloy metal, and its chief use is in the nickel steels and nickel cast irons.. It is also widely used for many other alloys, such as nickel brasses and bronzes, and alloys with copper, chromium, aluminum, lead, cobalt, silver, and gold. For more information on Nickel see our Encyclopedia Page on this topic. For Nickel Alloys we supply please visit our nickel Catalog Page. |
| Non Heat-Treatable Alloy | An alloy which can be strengthened only by cold work. |
