Effect of hydroextrusion pressure on the mechanism of molybdenum monocrystals plastic deformation

Considered are plastic deformation peculiarities of molybdenum monocrystals in the process of multiple-stage and single-stage deformation by hydroextrusion at 20-80% reduction under pressures of 1000-11000 atm. The effect of hydrostatic extrusion pressure upon the plastic deformation mechanism and mechanical properties is established. Multiple-stage deformation permits to considerably decrease the pressure value in practice as compared with the single-stage hydroextrusion, without deterioration of properties of deformed molybdenum monocrystals
