Abstract:  
AMS 2590 is a new specification that was released in December 2010. It was written by a team led by Peter Bailey, formerly a Staff Engineer with General Electric Aircraft Engines, to provide technical improvements to MIL-R-81841. MIL-R-81841 was released in 1972 and it has had an interesting history. It became an AMS document in 2001 and went back to being a MIL spec in 2004, with several revisions along the way. During all of these reversions; however, weaknesses in the spec were never addressed. Mr. Bailey has made AMS 2590 current with the advancements in equipment and procedures of this popular shot peening process.
