上产充毛大睾 Recovery SHEAMGHAI DUD TONO UHTVEREETTY Influencing factors The effect of strain For polycrystalline metals,complete recovery+lightly deformed. Single crystals of hexagonal close-packed metals such as zinc,deformed to large strains on only one slip system-completely recover. Single crystals of cubic metals if oriented for single slip and √ deformed in stage I of work hardening may recover almost. / deformed into stages ll or Ill of work hardening,then recrystallization may intervene before any significant amount of recovery has occurred. The recovered fraction of the property change increase with strain at a constant temperature. However,this trend may be reversed in more highly strained materials, because of the earlier onset of recrystallization.
