Fracture Mechanics Evaluation of B-1Materials. Volume II. Fatigue Crack Growth Data.

摘要

A total of 1764 fracture mechanics tests were conducted on fourteen alloys to develop property data for use in the B-1 design. Tests were performed on aluminum alloys 2024, 2124, 2219, 7049, 7050, 7075 and 7175; titanium alloy Ti-6Al-4V; steel alloys 9Ni-4C0-.20C, 9Ni-4C0-.30c and 300M; corrosion resistant steel PH13-8Mo; nickel alloy Inconel 718; and nickel-cobalt alloy MP 35N. The effects of product form, heat-to-heat variability, grain orientation, and heat treat condition on fracture behavior were investigated. The results of the tests are presented in tables and graphs in detailed and summarized forms. The effects of the various material and testing variables on fracture behavior are discussed.
