Loading Rate Effects and Fracture in a Tial Alloy
Published online by Cambridge University Press: 01 January 1992
Abstract
The room-temperature fracture toughness and tensile properties were evaluated as a function of loading rate, on a fully lamellar and nearly lamellar γ titanium aluminide alloy. The fully lamellar microstructure exhibited increasing toughness with increasing loading rate, however, all other mechanical property data indicated insensitivity to the loading rate. The fracture processes were dominated by translamellar, Mode I separation, and exhibited a process zone consisting of parallel slip traces/twins leading to formation of microcracks.
