METHOD FOR SOLDERING REFRACTORY DISPERSION-HARDENED NICKEL-CHROME BASE ALLOYS

摘要

FIELD: different branches of machine engineering, namely soldering refractory dispersion-hardened nickel-chrome base alloys. SUBSTANCE: method comprises steps of heat treatment of blanks for soldering; quenching them; heating until 1000 C and soaking for an hour; performing step type annealing; soldering at heating until 980+-20 C and soaking for 30 min; rapidly cooling part till 750+-30 C and soaking for 10-20 min. EFFECT: possibility of receiving high-ductility soldered joint without cracking.
