摘要：

A novel third generation Ni-based PM (powder metallurgy) superalloy WZ-A3 was evaluated for its hot compression behavior. Gleeble simulation tests on the extruded WZ-A3 samples over the temperature range of 1040 similar to 4130 degrees C and strain rate range of 0.0025 similar to 0.01 s(-1) were conducted. The samples compressed under different conditions were analyzed for grain size and microstructure evolution. The results indicate that under the compression conditions of temperatures from 1070 degrees C to 1100 degrees C, and strain rate from 0.005 s(-1) to 0.01 s(-1), a uniform fine grain around 4 mu m with gamma+gamma' microduplex structure can be obtained, and no abnormal grain growth and necklace grains are observed throughout. To validate compression property of the extruded WZ-A3 alloy, hot die forging was conducted successfully to make two prototype forgings with the size of 190 mm in diameter and 115 mm in height.
