Hot Deformation Behaviour Studies on 58Ni-39Cr Nickel Super Alloy by Thermo-Mechanical Simulation and Finite Element Method
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2019, Vol 9, Issue 3
Abstract
As there is an increased requirement of materials with superior quality and excellent properties, there is a search for appropriate materials to satisfy the increasing demands of product requirement, which has led to the invention of numerous new materials such as Nickel Super alloys that have superior properties, like great toughness, high oxidation resistance. These materials are inducing extensive interest in distinct fields like Oil and Gas Industries, Marine Industries, Nuclear Reactors industries. The forging of the Material needs to be done at a temperature zone to avoid failure of the Material. The torrid plastic deformations of the Alloy have been explored using Gleeble 3500 simulator and the consequences of forging aspects have been studied. It is then compared with the simulation studies carried out, using a finite element-based simulation software tool, DEFORMTM 3D. The results from both studies indicate that there is an upsurge in the flow stress as the forging temperature is lowered and the strain rate is increased. Flow softening is observed at every deformation conditions, which can be reflected by a crest followed by a drop-in flow stress with further straining.
