Abstract

The powder EP741NP superalloy with the initial ultrafine-grained microstructure after superplastic deformation and a solid-state joint in combination of the EP741NP superalloy and a cast intermetallic VKNA-25 alloy.This work was devoted to a study of microstructural changes and mechanical properties of the EP741NP superalloy with an ultrafine-grained (UFG) mixed-type microstructure. The deformation of samples with an UFG microstructure was carried out according to the uniaxial compression scheme in a wide temperature range of 750 –1125°C and strain rates of 5 ·10−4 –10−2 s−1. It has been established that the UFG microstructure is stable up to a temperature of 900°C. A temperature increase up to 1000 –1125°C led to the transformation of a UFG mixed-type microstructure into a fine-grained microduplex-type microstructure. It was also shown that a solid-state joint of intermetallic single-crystal VKNA-25 alloy with powder EP741NP superalloy could be obtained by pressure welding under temperature-strain conditions of superplasticity for the EP741NP superalloy. It was found that during pressure welding a transition diffusion zone was formed, the width of which was equal to 10 μm.
