RE: Differen between annealing & stress relieving?
I would suggest you look these terms up on the internet for more information.
RE: Differen between annealing & stress relieving?
I presume you mean for metals only. Certainly some plastics and probably wood can be stress relieved by treatment in water.

Yes indeed. They have posted a thread in another forum concerning cast iron and spheriodal cast iron and heat treatment. So, I believe this post was related.

Sounds like homework.

Stress relieving as the name implies relies on a combination of heat and stress to produce solid diffusion that results in elastic stresses being relieved. Typically, depending on the state of stress these temperatures are well under the annealing temperature. For instance, I've been able to stress relieve fine wire at 375C in order to straighten it while the typical full annealing temperature was over 300C higher. Keep in mind that during stress relieving you will get some recovery, and in age hardening systems you can get a precipitation reaction depending on the kinetics.

Yes, cracks are excellent at relieving stresses! Several years ago, a crack developed in my windshield after a rock hit it. Everybody pointed out that I had a crack, but I saw it as a stress relief.
