It is a process that produces conditions by heating and maintaining at a suitable temperature, and then cooling very slowly. It is used to induce softness, relieve internal stresses, refine the structure and improve cold working properties. </p> <p class="JNLC-copy">There are three basic stages in the annealing process. The first is the recovery stage, which results in softening of the metal through removal of crystal defects and the internal stresses. The second stage is recrystallization, where new grains nucleate and grow to replace those deformed by internal stresses. If annealing is allowed to continue once recrystallization has been completed, the third stage of annealing will occur. This phase is allows for new grain growth, in which the microstructure starts to coarsen and may cause the metal to have less than satisfactory mechanical properties.</p> <p class="JNLC-copy"><a href="/pages/other-techniques"><img src='http://static1.shopify.com/s/files/1/0014/5692/files/Back1.png' alt='' /></a></p> </div> 2008-10-10T20:18:45-04:00 annealing 498142 2008-10-10T20:18:45-04:00 145692 2008-11-04T11:58:25-05:00 <notextile> <div class="jnlc-container" id="jnlc-container"> <img src="http://static2.shopify.com/s/files/1/0014/5692/files/Annealing.jpg" width="360" height="200" class="floatLeft" /> <p class="JNLC-title">annealing</p> <p class="JNLC-copy">Annealing, in metallurgy and jewelry manufacturing, is a heat treatment wherein a material is altered, causing changes in its properties such as strength and hardness.
