Анотація


Approaches for modelling of polycrystalline metals and alloys using single crystal fundamental characteristics are considered. An example of modelling is the simulation of the hardening curve of a high-strength titanium alloy. The simulation results have proved satisfactory for further use of this approach in determining other characteristics used in process calculations of forming.
