what is stress relieving process for metals?

Answer 1

its a heat treatment process that is specified to remove residual stress from metal parts that result from them being processed. In my job, we have to stress relieve metal components that have been cold forged before the next operation.

Each metal has a stress relieving process best suited to it. Also, annealing is a heat treatment process intended to reorient the grain structure. Some people use the terms interchangably, but as someone previously noted, you should not confuse the two. In some metals the processes are nearly the same. In other metals they are dramatically different.

Some metals have standard heat treatments available through ASTM standards.

Answer 4

There are all types of stress, work stress? Something has to get done in a certain amount of time and i'm the only one on the job? I look at the job and put a plan together in my head and then kick @ss! Sexual stress? Hmmmmm I'll have to get back to you on this one ;-) Entertainment stress? I was stressing last night playing pool but my team pulled it out and we won 18-0 ;-)

Answer 5

in this mechanical life,most the people are suffering from mental stres and great tensions.It is just because we r loosing ethical values,thinking a'bout bad things,we r not at all keeping our minds fresh.
SOLUTION:::THE ONLY WAY TO ESCAPE FROM MENTAL TENSION AND TO HAVE A TRANQUIL MIND IS JUST DOING EXERSISES AND DOING MEDITATION.IF ANY ONE THINKS THAT HE IS IN AGREAT PROBLEM,HE SHOULD MADE HIMSELF MENTALLY PERFECT TO FACE THE PROBLEMS,
REMEMBER:::THE STRESS OR ANY THING U FEEL HARD JUST DEPENDS ON UR WAY OF THINKING,KEEP ALL THE THOUGHTS THAT DISTURB U AWAY FROM U,

Answer 6

A few points of clarification.

Stress relief and annealing are not exactly the same thing. There are several definitions for annealing, full annealing and process annealing as well as stress relieving.

Annealing or stress relieving are not to be confused with normalizing.

Various codes such as the ASME boiler and pressure code and the ANSI piping codes have specific definitions for these processes.

For carbon steels low temperatures like 300 to 400 deg F are not close to stress relief temperatures. The temperatures are up in the range of 1000 to 1600 deg F and can vary with actual material content. Normalizing can be in the 1500 to 1800 deg F range.

Answer 7

Atoms are arranged in a systematic manner in the space lattice in metals. The structure of arrangement could be "cubic,body centered cubic,Face centered cubic etc. When we want to alter metal properties such as tensile strength or hardness we can do so by heating up metal to a specific temperature and then quenching it in a suitable medium. Besides altering properties such a process introduces stresses in a metal. Hence the necessity to relieve stresses. This can be done by heating up the metal up to a specified temperature and allow it to cool gradually. Stresses will then be relieved.

Answer 8

It is called annealing.
After welding or fabricating the molecules tend to segregate and cause the metal to weaken. In the annealing process the metal is heated to a high temperature below the melting point and then cooled. This realigns the molecular structure of the metal thus retaining it's intended mechanical properties.

Answer 9

Residual strain from the working of metals particularily I beams can be alleiviated by allowing the metal to cool at a constant rate and very slowly

Answer 10

Normally a bake in the oven.

Typical : Bake at 375 deg.F for 24 hours minimum.


The guy above just described "Annealing" !
