Experimental and numerical investigations on sheet and tube hydroforming of inconel alloy 625

Abstract

The aim of this research study was to verify experimentally and newlinenumerically the feasibility of hydroforming process for producing defectfree newlinesheet metal parts from Inconel alloy 625 The pressurized fluid used inhydroforming is shown to have the effect of increasing the forming limits of newlinematerials that is deeper drawing depths are achieved without rupture Also newlineusing a specific pressure profile wrinklefree parts with deeper draws couldbe producedTube hydroforming is a well accepted production technology inautomotive industry while sheet hydroforming is used in selected cases for newlineprototyping and low volume production newline newline
