Beschreibung
Zusammenfassung:	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. ^ 10 cl, 5 dwg, 1 tbl, 8 ex
