FIELD: machine engineering, possibly restoration of articles operating at large cyclical loads and high temperature values. ^ SUBSTANCE: method comprises steps of cooling male part in liquefied nitrogen and introducing it into female part. Male part is made of refractory nickel alloy similar to that of female part. After equalizing temperature of assembly, it is heated till recrystallization temperature and subjected to isothermic soaking. It causes creation of structural and phase conversions in assembled parts. ^ EFFECT: improved quality of joints of parts. ^ 1 ex, 1 tbl |
