..., a polycrystalline single-phase metal has a grain structure, and within each grain a substructure may be present, or, in a polycrystalline long-range ordered binary alloy, a substructure of antiphase boundaries may exist within each grain. In a forging, the macroscopic flow lines may coexist with a structure...

The calibration of a precipitation-strengthening model should start with these submodels to ensure that desirable accuracy is available for these key input parameters. Error and uncertainty from submodel inputs have a strong effect...
