A process of relieving stresses and eliminating hard spots in ferrous metals Similar to annealing but employing a faster quench, or cooling cycle, to produce a more uniform grain structure and to remove hard spots without excessive softening
Heating iron-base alloys to approximately 100 °F (38 °C) above the critical temperature range followed by cooling to below that range in still air at ordinary temperature
Heating iron-base alloys to approximately 100 °F (38 °C) above the critical temperature range followed by cooling to below that range in still air at ordinary temperature
for ferrous alloys, austenitizing above the upper critical temperature, then cooling in air; the objective of this heat treatment is to enhance toughness by refining the grain size
A heat treatment process that has the object of relieving internal stresses, refining the grain size and improving the mechanical properties The steel is heated to 800-900°C according to analysis, held at temperature to allow a full soak and cooled in still air
The process of heating steel to a temperature above its transformation range, followed by air cooling The purpose of normalizing may be to refine grain structure prior to hardening the steel, to harden the steel slightly, or to reduce segregation
Heating a ferrous alloy to a suitable temperature above the transformation range and then cooling in air to a temperature substantially below the transformation range
Heating a ferrous material to a suitable temperature above the transformation range and then cooling in air to a temperature substantially below the transformation range
A process in which ferrous alloys are heated and then cooled in still air to room temperature to restore the uniform grain structure free of strains caused by cold working welding
