Fracture-Mechanism Maps for Nickel, Silver, Aluminium and Lead and Certain of Their Alloys

摘要

The mechanisms of fracture of round tensile specimens of a number of f.c.c. metals and alloys have been studied and reviewed. New observations have been combined with a large body of published data and used to construct two types of fracture mechanism maps which summarize the behavior. Maps are shown for commercially pure nickel, Nichrome, a Monel, nickel-2% thoria, Nimonic-80A and Inconel X-750; for pure silver; for pure and commercial 2S-grade Aluminum and for RR-58; and for two grades of lead. Certain generalizations about fracture behavior can be drawn from comparisons of the maps.
