ANNEALING OF EXTRUDED PEEKPlastics International
· Annealing is a stress relief process which occurs when the material is exposed to heat (air or fluid) above its glass transition point which allows the material to "decompress" back to a relaxed state. Annealing is important if you want a quality finished part out of your stock shape.

What is Stress-relief AnnealingDefinition Material
· Stress-relief Annealing. Stress-relief annealing is used to relieve stresses from cold working. In contrast to process annealing this heat treatment is usually performed after the product has been made. Care must be taken to ensure uniform cooling particularly when a component is composed of variable section sizes.

Effect of stress-relief annealing on the fatigue
· During the stress relief annealing process the dislocation pile-ups at the grain boundary moved into the grain to promote the reduction of the residual stress concentration at the grain boundary of the deformed sample (Fig. 8c and d). The lower stress concentration decreased the likelihood of fatigue crack initiation and the lower tensile

· In the present study Electrically assisted (EA) stress relief annealing for automotive springs is experimentally investigated. A concept of EA stress relief annealing is to reduce the process time by superimposing the effect of electroplasticity on that of the elevated temperature. In EA stress relief annealing the temperature of a cold-coiled spring specimen is rapidly increased to the

Annealing vs Normalizing vs Tempering vs Quenching
Stress relief annealing which many people call it low temp-annealing refers to heating steel in temperature between 500 to 600 degrees Fahrenheit. The next step of the process is letting steel stay at that temperature for a while. Then the metal has to be gradually cooled down below 300 degrees Fahrenheit in furnace controlled temperature.
