Article Title: Analyzing the Effect of Temperature on Alloy Steel Forging Simulation Using Deform 3D
Abstract
The purpose of this study is to examine the influence of temperature on forging of a rectangular billet of AISI 4120 alloy steel using the 3D Deform version 11 software. The simulation was performed with 0.3 coefficient of friction on a metal forming (lubricated) process and the part is intended for application in aerospace and oil and gas industries. Three modules of deform software were defined to execute the simulation: pre-processing, simulation, and postprocessing. The pre-processing in forging employed standard data— material selection, billet drawing, top and bottom dies design, meshing and simulation control. After 120 steps, the postprocess estimation of deformation temperature, effective strain and stress, total velocity, and total displacement were obtained on the billet of material at temperatures of 800o C, 1000o C, and 1200o C. According to the results, effective strain and stress dropped with rising forging temperatures and the total displacement and velocity reduced, and the final temperature rises.
