FIELD: plastic working of metals and alloys, possibly manufacture of large-size axially symmetrical parts for important designation, for example discs for gas turbine engines of multi-phase refractory alloys possibly on base of nickel and titanium.
SUBSTANCE: method comprises steps of rolling at controlling temperature and deformation rate at rolling in temperature range of super-plasticity; controlling temperature of rolled portion of blank and subjecting it to heat treatment; combining rolling process and out-of-contact super-plastic deformation of rolled portion of blank while selecting values of deformation rate at rolling and temperature of rolled portion of blank.
EFFECT: enhanced uniformity of material structure of part.
