3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 beta transus, n—the minimum temperature at which the alpha plus beta phase can transform to 100 % beta phase.
3.1.2 capability-aged, adj—the condition of the material that is obtained if, following solution treatment, a sample of the
mill product is subjected to an aging treatment such as given below, for certification testing.
3.1.2.1 Age for 6 6 0.25 h at 923 6 25°F (495 6 14°C).
3.1.2.2 Remove from furnace and air cool to room temperature.
3.1.3 cold work, n—any mechanical deformation process performed below the recrystallization temperature which results in strain hardening of the material.
3.1.4 hot work, n—any mechanical deformation process performed above the recrystallization temperature.
3.1.5 lot, n—the total number of mill products produced from the same melt heat under the same conditions at essentially the same time.
3.1.6 solution-treated, adj—the condition of the material that is obtained if, following the final hot-working or cold-working operation, the mill product is rapidly quenched, for example, by water quenching, from a temperature above 1112°F (600°C).
3.1.7 unannealed, adj—the condition of the material that is obtained after the normal hot-working or cold-working operation used for fabrication of the mill product. There are no subsequent heat treatment requirements.
