By segregating the carbides along the grlain.boundariel it is possible to incre.. e
the high-temperature strength. Tile best properties are obtained for a combina

Ni-Cr alloys by preliminary jacketing at an increasedistress level and working

Translation: A study was made of a high-alloy heat-re6istant alloy whose
chemical composition corresponded to technical specifications. Heat treatment
vas carried out under the following conditions: quenching from 12200 for
four hours, cooling in the air, quenching from 9500 for two hours, cooling in
the air, aging at 9800, 25, 100, 200, and 500 hours. After aging, the struc-
ture and properties of the alloy vere investigated. It was demonstrated that
during the process of prolonged aging of the alloy at
