A review on hot stamping
The production of high strength steel components with desired properties by hot stamping (also called press hardening) requires a profound knowledge and control of the forming procedures. In this way, the final part properties become predictable and adjustable on the basis of the different process parameters and their interaction. In addition to parameters of conventional cold forming, thermal ...
متن کاملMetal Forming Modelling Materials Properties Critical to Simulation of Hot Stamping
Reliable simulation of hot stamping process requires accurate material data. This paper describes the development of computer models that can provide many of the material data required, including TTT/CCT phase transformation diagrams, temperature dependent physical and thermophysical properties, as well as temperature and strain rate dependent mechanical properties including high temperature st...
متن کاملEffect of Constitutive Equations on Prediction Accuracy for Springback in Cold Stamping of TRIP1180
The objective of this study is to evaluate the effect of constitutive equations on the prediction accuracy for springback in cold stamping with various deformation modes. In this study, two types of yield functions—Hill’48 and Yld2000-2d—were considered to describe yield behavior. Isotropic and kinematic hardening models based on the Yoshida–Uemori model were also adopted to describe hardening ...
متن کاملCoupled numerical simulation of hot stamping process and experimental verification
Hot stamping process is a high non-linear process showing the effect on thermal, mechanical and metallurgical phenomena as they relate to each other. In order to carry out this coupled numerical simulation, fundamental thermal properties such as interfacial heat transfer coefficient and convection heat transfer coefficient as well as crucial mechanics properties were first investigated. Hot sta...
