| Abstract Scope |
Anisotropic microstructure and mechanical characteristics, material selection constraints, flaws, and high cost are still obstacles that AM must overcome. Grain size is an important microstructure characteristic that is directly related to properties. It is still not possible to create an accurate physics-based analytical model for process-structure-property prediction. The author develops the thermal model while considering the geometry of the molten pool and heat transfer boundary. Next, the heating and cooling processes are simulated for the grain size, taking into account JMAK, thermal stress, and grain refining. The CET model, thermal dynamics, and Bunge calculation are used to simulate the texture. The visco-plastic self-consistency model gains the properties of the impacted materials after determining the texture distribution. For increased accuracy, the updated peoperties are then incorporated. The Ti64 alloy was selected to validate the analytical models in a multi-phase setting, offering a new paradigm to modeling microstructural evolution with varying properties. |
