  skos:definition "1. Stress-relieving is a technique to remove or reduce the internal stresses created in metal. These stresses may be caused in a number of ways, ranging from cold working to non-uniform cooling. Stress-relieving is usually accomplished by heating a metal below the lower critical temperature and then cooling uniformly. Stress relieving is commonly used on items like air tanks, boilers and other pressure vessels, to remove a portion of the stresses created during the welding process. (Wikipedia). 2. Stress relieving is a heat treatment process that aims to reduce or relieve stresses in workpieces caused by thermal or mechanical processing.(https://www.aalberts-st.com/processes/stress-relief/)"^^ns0:None ;
