Abstract

In order to study the effect of solution temperature on the microstructure and properties of GH4099 alloy ring forgings, a heat treatment test was designed with solution treatment temperature of 1 080, 1 100 and 1 120 ℃, holding time of 1 h and aging treatment system was 900 ℃ and the holding time was 5 h. Then, the microstructure analysis and mechanical properties test were carried out. The effect of solution temperature on the microstructure and properties of GH4099 alloy ring forgings was investigated by SEM, EPMA, JMatPro software and mechanical experiment detection. The results show that, after the solid solution treatment at 1 080, 1 100 and 1 120 ℃, the average size of the γ′phase is 47.3, 48.5 and 49.3 nm, respectively, and the volume fraction is 30.1%, 31.0% and 29.9%, respectively. It can be seen that the solid solution temperature has little effect on the size, content and distribution of γ′phase. With the increase of solution temperature, the hardness of the alloy decreases. The granular M23C6 carbide in the crystal gradually dissolved with the rise of solid solution temperature. When the temperature reached 1 120 ℃, the M23C6 in the crystal almost completely dissolved. The fine and uniform grain can be obtained below 1 100 ℃; when the temperature is above 1 100 ℃, the grain size grows obviously, and the M23C6 carbide precipitate in a chain shape at the grain boundary after aging, which makes the grain boundary change from flat to curved. The curved grain boundary can effectively improve the rupture life of the alloy. The grain structure near the fracture of the durable specimens is elongated, and there are a lot of voids at the grain boundaries, which indicates that intragranular fracture is the main mechanism of crack initiation and propagation in the alloy. In addition, uneven internal texture and mixed crystal phenomenon occur in the alloy when solution treatment temperature is 1 120 ℃. Therefore, the best solution treatment temperature for GH4099 alloy ring forgings is 1 100 ℃.

Key words： GH4099 alloy; solution treatment temperature; microstructure; mechanical property; hardness; rupture life
