Friction welding of high-strength casting nickel alloy VZh172L

Abstract

Technological parameters of continuous drive friction welding of cast nickel superalloy VG172L have been chosen. The alloy was welded in the same name combination and also with the deformed variant of nickel superalloy VG172, mechanical properties and structural peculiarities of produced welded were studied.
