Abstract: The present disclosure discloses a method and system for designing a solution heat-treatment process of a single-crystal superalloy, and relates to the field of numerical simulation-material processing crossover techniques. The method includes: determining a solidus temperature distribution of an as-cast single-crystal superalloy sample based on a relationship between an element concentration and a solidus temperature according to an element concentration distribution extracted from the as-cast single-crystal superalloy sample; subjecting the as-cast single-crystal superalloy sample to solution heat-treatment simulation by a phase-field method to obtain a post-treatment element concentration distribution after a simulation time step of heat preservation at an incipient melting temperature; determining a segregation coefficient of each element; when segregation coefficients of all elements are within a preset range, denoting all incipient melting temperatures and corresponding current simulation times as solution heat-treatment simulation results; and determining an actual solution heat-treatment process of the as-cast single-crystal superalloy sample.
