Abstract

The technology of powder metallurgy is widely used in the industry for the production of deformed semiproducts (rods, sheets, strips, forgings) from refractory metals, molybdenum (of grade M-PM) in particular. Molybdenum in the form of deformed rods is used in structures operating at a temperature of up to 2000°C. The requirements on the stability of the mechanical properties of structural materials are very strict (especially at room temperature). The stability of the mechanical properties of molybdenum rods is affected substantially by the types and conditions of the deformation treatment of the sintered preforms. The present work is devoted to the mechanical properties and parameters of rods from powder molybdenum obtained by extruding and rolling of sintered preforms with various degrees of deformation.
