Abstract

An efficient closed-form technique was introduced and developed for the determination of interfacial heat transfer coefficient (IHTC) accurately and cost effectively from typical heat transfer test data, which is directly related to hot/warm forming conditions. Based on finite element (FE) heat transfer analysis for a typical test, a one dimension heat transfer model was proposed. A numerical procedure has been developed and implemented for determining the IHTC. The closed-form method has been validated by the comparison of experimental, numerical and finite element results. For hot/warm forming process, the effect of pressure on the IHTC of Ti-6Al-4V work-piece and H13 steel tool were investigated. A finite element model of Ti-6Al-4V alloy hot upsetting process was built in FE software DEFORM using the IHTC predicted from the closed-form method. The variation of IHTC with the pressure was implemented into DEFORM subroutine as boundary conditions in the process modelling. The temperature distribution at different locations of the work-piece was studied. The stress distribution was also predicted. The data obtained can provide information for better process control, tool analysis, and more accurate FE forming process modelling.
