ASTM WK40062

    Revision of E2860 - 12 Standard Test Method for Residual Stress Measurement by X-Ray Diffraction for Bearing Steels

    (What is a Work Item?)

    Active Standard: E2860 - 12

    Developed by Subcommittee: E28.13 | Committee E28 | Contact Staff Manager


    1. Rationale

    There are two main items in the rationale for revisions. 1. To continue with our long-term goal to expand the standard to additional polycrystalline materials including Titanium, Aluminum, and Nickel based alloys. Going forward we need to decide how this will be approached in the standard. Are there unique considerations that will require sections of the standard to be devoted to specific materials? B: An Interlaboratory study to determine the precision of the test method (E691) needs to be completed by May 2017. There are no national reference standards available so we will need to create our own stressed samples. ASTM has offered their assistance in the creation of these samples. We will need to discuss what materials should be included as well as how to deal with various factors such as creep. I would also like to discuss the possibility of using neutron diffraction to non-destructively measure a subsurface gradient, and then use destructive x-ray diffraction to correlate the results.
