Based on the Explicit/Standard modules of software ABAQUS, a 3D finite element model of Ni-Cr-W-Mo superalloy workpiece with strange shape multi-pass is built. The distribution and variation features of stress-strain, hot spinning regular pattern, and common defects are investigated in the forming process for the Ni-Cr-W-Mo superalloy workpiece with strange shape. The results show that by taking some factors, such as the defects forming, minimizing forming pass, etc into account, the spinning gap should be bigger than 3.7mm. The gap between blank and mandrel is quite small at the region near the central axis, however, the gap near the oral part of workpiece increases enormously.
