“…In addition, the mathematical model is a vital way to depict the relationship between deformation conditions and rheological features, as well as the microscopic structure evolution in alloys [ 7 , 17 , 18 , 19 , 20 ]. Meanwhile, accurate mathematical models are essential to analyze/forecast material deformation behavior and the evolution of the microstructure by the finite element method (FEM) [ 21 , 22 , 23 ]. Recently, for the deformed P/M superalloys, some accurate mathematical models were established.…”

The dynamic recrystallization (DRX) features and the evolution of the microstructure of a new hot isostatic pressed (HIPed) powder metallurgy (P/M) superalloy are investigated by hot-compression tests. The sensitivity of grain dimension and DRX behavior to deformation parameters is analyzed. The results reveal that the DRX features and grain-growth behavior are significantly affected by deformation conditions. The DRX process is promoted with a raised temperature/true strain or a reduced strain rate. However, the grains grow up rapidly at relatively high temperatures. At strain rates of o.1 s−1 and 1 s−1, a uniform microstructure and small grains are obtained. Due to the obvious differences in the DRX rate at various temperatures, the piecewise DRX kinetics equations are proposed to predict the DRX behavior. At the same time, a mathematical model for predicting the grain dimension and the grain growth behavior is established. To further analyze the DRX behavior and the changes in grain dimension, the hot deformation process is simulated. The developed grain-growth equation as well as the piecewise DRX kinetics equations are integrated into DEFORM software. The simulated DRX features are consistent with the test results, indicating that the proposed DRX kinetics equations and the established grain-growth model can be well used for describing the microstructure evolution. So, they are very useful for the practical hot forming of P/M superalloy parts.

“…The Forming Limit Diagram (FLD) is actually thought the best great program to get the protected strain location for every sheet metal in a variety of strain circumstances as well as ration. In this specific research newspaper [26], significance of vital process parameters especially, punch velocity, Blank Holder Pressure (BHP) and temperature on FLD associated with a Ti-6Al-4V alloy are actually examined. Taguchi technique was used to figure out the effect of the parameters on little strain and substantial stress.…”

The present work focuses on the prediction of onset of fracture for thin-walled metallic sheets used for forming complex shape and lightweight components for aerospace applications. The Lou-Huh ductile damage model has been used along with Barlat 1989 anisotropic yielding function for the prediction of fracture limits of Inconel alloy in different stress states, namely, pure shear, uniaxial tension, pure strain and equi-biaxial tension. Nine different types of specimens have been deformed experimentally till the occurrence of fracture using simple tensile test and stretch forming setup. The principal stresses at the onset of fracture have been determined experimentally and numerically and plotted in the major-minor strain space and, further, have been transformed into the effective plastic strain to fracture vs. stress triaxiality space. The fracture sites in the numerical simulations have been found to be consistent with the experimental results. Cockcroft-Latham, Brozzo, Oh and Rice-Tracey model have also been used for determining the fracture locus but the Lou–Huh model has only been found to accurately predict the fracture limit in all the stress states for a wide range of stress triaxiality as it considers the effect of shear-linkage of voids.
