摘要	The stress-rupture life of a nickel-based superalloy increases with increasing yttrium addition up to 0.013% Y, then decreases. The carbide morphology changes from continuous platelets to discrete blocks. Eutectic volume increases with increasing yttrium concentration. This results in the drop of rupture life when excess yttrium doped. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
