A D V A N C E D M A T E R I A L S & P R O C E S S E S | S E P T E M B E R 2 0 2 0 3 4 One such standard currently in draft form is on “Residual Stress Classifica- tion, Metallic Structural Alloy Products, and Finished Parts.” There are a num- ber of industry specifications and stan- dards for measurement, but there is no standard for how bulk residual stress- es are defined within product require- ments and definitions. Surface residual stresses are indirectly specified for sur- face treatment processes by means of peening intensity factors, and valida- tion methods through use of process setup and oversight tools such as Al- men strips. For bulk residual stresses, the magnitude and spatial distribution are largely not directly or indirectly incor- porated into product definitions that are provided to suppliers, but have been the focus of much research and applica- tion within the heat treating communi- ty. Bulk residual stresses are extremely important and impactful to both down- stream manufacturing operations (i.e., machining and associated distortion) and component service behavior (i.e., yield behavior or fatigue life). The draft industry standard is being worked on by the Residual Stress Technical Com- mittee in preparation for submission to the SAE standards committee for review and balloting. This newly formed committee is just beginning, but has made significant progress on a number of fronts. The ability to develop a technical commit- tee focused on a technical topic area of interest to a group of ASM Internation- al members enables the establishment of “home rooms” or “communities of practice” that allow members to volun- teer and be active within a specific in- terest area.
