Abstract

For the delta process (DP) of GH4169 high temperature alloy, the effect of d phase content on its hot deformation behavior and evolution of microstructures was studied systematically by isothermal compression test with a strain rate range 0.005-0.1 s^-1at temperature range 950-1010℃. The results indicated that the true stress–true strain curves for GH4169 alloys with different initial d phase contents of 0, 3.65% and 8.14% may be characterized with the feature of single peak curves, and the constitutive equation could be all expressed by a hyperbolic-sine Arrhenius-type equation. The corresponding activation energies of deformation were 441.3, 445.8 and 487.7 kJ/mol, respectively. The main soft mechanisms for GH4169 alloys with different initial d phase contents during hot working were all dynamic recrystallization (DRX). As the increase of δ phase content, the critical strain and grain size of DRX decreased, and the fraction of DRX increased. The DRX nucleation for the solution treated alloy might mainly rely on the bulging of original grain boundaries, while the boundaries between the d phase and matrix were the nucleation sites for DRX in the pre-precipitated GH4169 alloys. Thus, the existence of d phase can stimulate the occurrence of DRX.
