The forging processes of P/M FGH95 alloy disk using ring like billet were simulated by large deformation rigid visco plastic finite element method (FEM). Some surface defects like laps and underfill were predicted. The relative contacting length between billet and die (the ratio of the contacting length to the initial height of billet) was proposed as a criterion to judge whether the lap defects would occur or not.
