Army Research Lab Uses XRD to Evaluate Shot-Peened Aerospace Materials

摘要

THE U.S. MILITARY is in fat-trimming mode and is cutting aerospace budgets through aircraft sustainment and the implementation of lighter, stronger aerospace materials that will reduce aircraft weight without sacrificing strength. Since shot peening is a useful tool for accomplishing both of these goals, the ability to evaluate shot peenings results is just as important. The Army Research Lab (ARL) in the Aberdeen Proving Ground in Maryland was commissioned by the U.S. Army Aviation and Missile Research Development and Engineering Command to evaluate variations of shot peening intensity on several aerospace materials with x-ray diffraction (XRD).
