As　a　nickel-based　alloy,　GH4169　has　the　properties　of　excellent　corrosion　resistance,　high　temperature　oxidation　resistance　and　high　creep　resistance.　In　this　paper,　the　compression　creep　behaviors　of　cylinder　entangled　wire　materials　(CEWMs)　made　from　metal　wires　(GH4169　nickel-based　alloy,　304　stainless　steel)　were　investigated　at　elevated　temperatures　(from　400　°C　to　500　°C).　The　performance　degradation　of　the　two　materials　was　evaluated　by　the　variation　amplitude　of　four　mechanical　properties　parameters　and　material　characterization　methods.　The　results　indicated　that　both　of　304　CEWMs　and　GH4169　CEWMs　suffered　a　significant　performance　degradation　at　elevated　temperatures,　and　both　of　the　two　CEWMs　showed　a　much　serious　performance　degradation　above　450　°C　(tempering　temperature).　Compared　to　the　304　CEWMs　at　the　tested　temperatures,　the　GH4169　CEWMs　obtained　better　creep　resistance.　It　is　therefore　concluded　that　the　GH4169　CEWM　is　an　excellent　material　that　can　replace　the　commonly　used　304　CEWM　at　elevated　temperature　work　conditions.　©　2024　Elsevier　B.V.
