Method for processing rods of material in order to give them plasticity in low temperatures, and applications of a material subject to processing in order to manufacture elements working in liquid nitrogen

摘要

the subject of the invention is a treatment for giving him rods material yield stress at low temperatures, comprising odksztau0142canie plastic, in which a steel material is used ferrytycznu0105.steel heat treatment before the subjected only odksztau0142caniem plastic, which is pressing hydrostatic performed in at least six stages of progressively decreasing value of deformation and combining an accumulated deformation value of greater than or equal to 2 5, with pressing hydrostatic drive chu0142odzu0105c material at room temperature.the subject invention is furthermore applicable steel ferritic deformation in the manufacture of the plastic surgeon working at liquid nitrogen temperature.
