Fatigue fretting is the process of crack formation and progressive crack growth at a location in a mechanical system where two components are in contact and undergoing a vibratory loading. A new ASTM International standard provides insight on what conditions promote fretting fatigue and offers approaches to design an experiment to assess it. ASTM E2789 , Guide for Fretting Fatigue Testing, was…, ASTM Committee E08 Next Meeting:, May 16-20, May Committee Week, Anaheim, Calif., Technical Contact:, Richard W. Neu, Georgia Institute of Technology, Atlanta, Ga., Phone: 404-894-3074; rick.neu@gatech.edu ASTM Staff Contact: Jeff Adkins, Phone: 610-832-9738; jadkins@astm.org ASTM PR Contact: Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org R elease #8809

X-ray diffraction has become a popular means of residual stress measurement in the aerospace materials field over the last 50 years. A proposed new guide being developed by ASTM International Committee E28 on Mechanical Testing will provide the necessary information to obtain the most reliable residual stress values as well as identify and evaluate potential errors in measurement, paving the way…

Creep-fatigue testing simulates the loading and temperature conditions experienced by turbine components of aircraft engines, nuclear reactor components and fossil power plant components during service. With increasing need for cyclic operation during peak power demands, reliable creep-fatigue test data is necessary for the life assessment of aging power plants. A new ASTM standard, ASTM E2714 ,…
