Claim One:
1. A computing system for assessing a manufactured metal alloy component for a turbine engine, the computing system comprising at least one computing device and instructions embodied in one or more non-transitory machine accessible storage media, the instructions executable by the at least one computing device to cause the computing system to: predict time-dependent crack growth behavior in a manufactured metal alloy component having a crack by: performing finite element modeling of the component; obtaining transition criteria from the finite element modeling; performing a fractographic evaluation of the crack in the component; creating a fracture mechanism map for the component based on the fractographic evaluation of a surface of the crack, the fracture mechanism map indicating operating conditions under which a transgranular crack growth mechanism is predicted to occur and operating conditions under which an intergranular crack growth mechanism is predicted to occur, wherein the operating conditions under which an intergranular crack growth mechanism is predicted to occur are different than the operating conditions under which a transgranular crack growth mechanism is predicted to occur; and determining, from the fracture mechanism map and the transition criteria, a modified dwell transition temperature for the component, the modified dwell transition temperature indicating a temperature at which the crack growth behavior of the component is predicted to transition from a transgranular crack growth mechanism to an intergranular crack growth mechanism; with the modified dwell transition temperature, generate a life prediction for the component; and modify one or more of: a design of the component, a material selection for the component, and a maintenance plan for the component, based on the life prediction.
