Abstract：

The blade forming process was studied in order to decide the bar-extrusion and head-upset as the process route.The engineering software Pro/E was used as a geometric modeling tool to create the die-cavity.In order to study the effect of friction coefficient and provide theoretical direction in forming blade with one rabbet,the 3D thermal-couple mechanical simulation for forming IN718 alloy blade with one rabbet was carried out and the temperature field,the equivalent stress field and load-time curve were analyzed under different friction conditions by the finite element technique software DEFORM.After that,the reasonable blank,temperature field,equivalent stress field and load-time curve could be obtained.The research is important to optimize the processing parameters of blade forming and to develop the precision forging of blades in aero-engine.
