ASTM International (West Conshohocken, PA) is proposing a new standard, WK21984, “Test Method for Creep-Fatigue Crack Growth Rate Testing.” It is being developed by Subcommittee E08.06 on Crack Growth Behavior, part of Committee E08 on Fatigue and Fracture.
According to the task group co-chairs, Ashok Saxena, Ph.D., who is the dean of the College of Engineering at the University of Arkansas, and Bilal Dogan, Ph.D., who is the senior project manager at EPRI in Charlotte, NC, the standard is being developed so that power plants and aircraft engines can be designed to operate at higher temperatures. Higher operating temperatures will boost energy conversion efficiencies. Dr. Saxena also noted that the service lives of the components at high temperatures are determined by the creep-fatigue properties of the materials used.
Committee E08 plans to meet May 18–21 in Vancouver, BC, Canada. Those interested in participating in the development and round robin testing of WK21984 can contact Dr. Saxena at 479-575-3054 or firstname.lastname@example.org.
