Effect of Hot Deformation Parameters on the Dissolution of γ′ Precipitates for As-Cast Ni-Based Superalloys
Source abstract
Abstract
The dissolution and redistribution of γ′ precipitates for homogenized as-cast superalloy GH4720Li were systematically investigated during heat treatment and hot deformation processes. The results showed that the volume fraction of γ′ precipitates decreased with the increase of temperature (varying in 1080-1160 °C) during heat treatment. At the initial stage, the volume fraction of γ′ precipitates rapidly decreased with the prolongation of holding time, a dissolution equilibrium of γ′ precipitates, including invariable dendrite morphology and volume fraction, was subsequently reached once the holding time exceeded 20 min. Compared with the above static dissolution, the dynamic dissolution of γ′ precipitates was strikingly accelerated and enhanced with the increase of strain and decrease of strain rate. In such case, the morphology of γ′ precipitates after hot deformation changed significantly from initial dendrite-like to fine sphere shape. Three concomitant processes including dislocation shearing, dissolution and reprecipitation, were considered as playing an essential role in the redistribution of γ′ precipitates during hot deformation.
