Abstract
The constitutive principles are utilized to simulate the densification and deformation of K4169 superalloy powder within the turbine shroud segment compact. To obtain the necessary modeling parameters, the models are calibrated through carefully designed experiments. The Deform V13.0 software is employed to replicate the sintering process of the workpiece and assess the performance of the nickel alloy. The effects of sintering time on volume, density, stress, powder flow velocity, and deformed morphologies are illustrated through a comparison of predictions from the finite element method with empirical measurements. The finite element models accurately predict several phenomena, including that longer sintering durations result in reduced distortion, increased density, and higher stress.
