Effect of the thermal component of barothermal treatment on the carbide phase component of a cast nickel alloy

Synchrotron X-ray diffraction analysis of a cast nickel alloy after barothermal action

“…As a result, AE atoms migrate from γ solid solutions and penetrate into the crystal structure of the γ' intermetallic com pound, and the chemical composition of carbides in the alloy changes [5], leading to a distortion of the ideal hcp cell ( = a γ = 3.5800 Å), in which the inter atomic distances in different crystallographic direc tions are different. Since it is difficult to develop a crystal chemistry model for the alloy structure after…”

“…Many modern works [1][2][3][4][5][6][7] inves tigate the effect of barothermal treatment (BTT) on the formation of the γ' phase and the evolution of the morphology and chemical composition of carbides and the crystal structure of high temperature alloys due to dynamic development of hot isostatic pressing (HIP) of nickel superalloys. These works analyze a change in the morphology of γ' particles [1,6,7] and the morphology and composition of carbides [5] in nickel superalloys. The crystal structures of these alloys were studied by X ray diffraction (XRD) [2,3].…”
