Mechanism of Subcritical Crack Growth Under Sustained Load.
Abstract
Studies were conducted to determine whether subcritical crack growth under sustained load was related to creep-rupture or hydrogen embrittlement. Crack growth in titanium alloys was strongly affected by variations in hydrogen content, indicating that hydrogen embrittlement was a primary factor. Aluminum alloys, which are not susceptible to hydrogen embrittlement, showed no evidence of subcritical crack growth under sustained load. Variations in the hydrogen content in titanium alloys also affected creep resistance and fracture toughness, both of which influenced the susceptibility to subcritical crack growth under sustained load.
