Effects of Alloy Elements Nb and V on the Microstructure and Expansion Property of 4J32 Austenite

Using optical microscope， scanning electron microscope， and dilatometer etc， this work investigated the effects of alloy elements Nb and V on the austenite microstructure and expansion property of 4J32 alloy. The results indicated that when the addition amount of Nb was 0.1%， the pinning effect on t...
