【Abstract】 Molybdenum has high mechnical property and hardness, but its low plasticity hinders its extensive use . The effect of molybdenum materials,process specification, shape and environment on the plasticity of molybdenum was introduced. According to the theory of dislocation and stress concentration, the relation between the deformation and fracture of molybdenum was discussed. The main ways which increased the plasticity of molybdenum were put forward.更多还原
