| Abstract: | Study is made on the use of complex pressing(die pressingfollowed by cold isostatic pressing) for small hard metals blank.Thebending strength of sintered product of complex pressed small blank isdistinctly increased and the service life is increased by more than 50y0.However, the use of complex pressing for small blank has a limitationdue to. dimension influence. |
