摘要: An advanced forming process involving hot and cold-die quenching, also known as HFQ®, has been employed to form AA6082 tailor welded blanks (TWBs). The HFQ® combines both heat treatment in a single operation, whereby upon heating the TWB, it is stamped held between cold tools quench component room temperature. material therefore undergoes temperature, strain rate or path changes during operation. In this paper, finite element model (FEM) was developed investigate formability deformation characteristics of TWBs under conditions. Experimental results, i.e. distribution, were used compare validate simulation results. A good agreement experiment achieved. dependent limit prediction implemented into FE capture complicated failure features formed TWBs. It found from that speed important effects on occurrence position, where mode for 1.5-2 mm may change localised circumferential necking parallel weld necking.HFQ® registered trademark Impression Technologies Ltd.
