In the context of additive manufacturing, it is also essential to consider how alloying elements affect the formability of these alloys. In this study, three developed CoNi-based superalloys, named as AlTa, AlTaNb and AlTaTi, were fabricated using laser directed energy deposition, and followed by homogenization and aging treatment. The effect of alloy composition on additive manufacturing formability, microstructure and mechanical properties was analyzed. The AlTa and AlTaNb specimens show good additive manufacturing formability, but the AlTaTi specimen appears several long cracks along deposition direction. The addition of Ti is not conducive to the additive manufacturing formability of CoNi-based superalloys. The volume fraction of the γ′ phase in the three heat-treated specimens is 65∼70 %, and the average size is about 200 nm. The AlTa specimen maintains its tensile strength without softening from room temperature to 900 °C, possessing an excellent yield strength of 471 MPa at 900 °C. The AlTaNb and AlTaTi specimens achieves higher tensile strength at room temperature due to the strengthening effect of Nb and Ti elements, but underwent premature intergranular fracture during high-temperature tensile testing due to the insufficient grain boundary strength.

The BP model optimized by the bald eagle search algorithm (BES-BP), the BP model optimized by the sparrow search algorithm (SSA-BP), and the BP model optimized by the gray wolf optimization algorithm (GWO-BP) were developed for high-precision prediction of flow stress. The above models were compared by using the mean square correlation coefficient, root mean square error, and average absolute relative error between the predicted and experimental flow stress.

A hot processing map based on the dynamic materials model was developed by using the flow stress predicted in the framework of the BES-BP model, and EBSD analysis was performed as well. The results show that the degree of dynamic recrystallization increases with an increase in the power dissipation factor, and the formation of deformation bands is the main cause of instability. The minimum critical stress for inducing dynamic recrystallization of the alloy was found to be 13.13 MPa at 890 °C/0.0005 s<sup>−1</sup>.
