Abstract：Near-isothermal canned forging for molybdenum powder sinter was investigated by using finite element software. The influence of process parameters (temperature, friction coefficient and forging rate) on strain distribution was discussed. The results show that the average equivalent strain increases with the rising of forging temperature, but the corresponding deformation is non-uniform. Average equivalent strain increases with the increase of friction coefficient, meanwhile, the fracture crack easily occurs owing to non-uniform deformation. The effect of forging rate on strain is not obvious. Through analysis on the orthogonal experiment, the effect of temperature on deformation uniformatity is the most remarkable.
