METHOD FOR MAKING THIN SHEETS Russian patent published in 2000 - IPC

FIELD: plastic metal working, namely hot rolling of thin sheets of hard-to-form titanium alloys with high ductility of products ( bending angle more than 105 degrees). SUBSTANCE: method for making thin sheets with thickness less than 2.5 mm comprises steps of hot rolling of blanks; applying onto surface of blank heat insulation coating with thickness 0.08-0.30 mm and with non-uniformity degree up to 5% by electric-arc deposition of aluminium wire; impregnating applied coating with chemical reagent; heating blank and ironing it in rolls of rolling mill ar reduction degree 2-5%. Before finishing surface of rolled sheets carrying out hydraulic abrasive cleaning of said surface for removing deformed layer of coating. EFFECT: possibility of making thin sheets of hard-to-form titanium alloys with high ductility degree. 2 cl, 1 tbl
