TREATMENT METHOD OF SEMI-FINISHED PRODUCTS FROM TH-1 TITANIUM NICKELIDE

摘要

FIELD: metallurgy. ^ SUBSTANCE: treatment method of semi-finished products from TH-1 titanium nickelide by preliminary heat cycling at intervals of martensitic conversions in twisting mode is proposed. Heat cycling at intervals of martensic conversions is repeated until steady-state values of deformation responses are obtained; at that, semi-finished product is heated from martensitic state T= 295 K to austenitic state T= 500 K and cooled back to martensitic state. ^ EFFECT: obtaining deformation characteristics of stable effect of reversible deformation. ^ 4 tbl
