【 摘 要 】

In the search for a remedy to increase the fracture toughness of NiAl, the effect of rhenium and aluminum oxide addition is explored. Using a powder metallurgy processing route an optimum composition of NiAl-Re-Al2O3 material is found which manifests K-IC over two times higher than as-received NiAl sintered under the same conditions.
