摘要：

Observations have been made of fracture surfaces deformed at low strain rates (3. 3 and 42 multiplied by 10** minus **3s** minus **1) in tension at temperatures from 20 to 1000 degree C, that is, above and below the order/disorder transformation temperature of 950 plus or minus 10 degree C. From 20 to 700 degree C, transgranular fracture occurs via the nucleation, growth, and coalescence of microvoids; high ductilities are obtained (34 to 44 pct). From 700 to 960 degree C, the fracture mode changes from transgranular to intergranular and ductility falls to a minimum of 4 pct. At 1000 degree C a third mode operates consisting of localized dynamic recrystallization followed by boundary sliding of recrystallized grains; ductility rises sharply. The underlying mechanisms are supported through additional experiments performed at higher strain rates.
