Web13 de mar. de 2024 · Moreover, an increment of 100 MPa for yield strength was achieved when the creep strain increased from 0.075 to 0.21%. For low creep strain, sample was controlled by the dislocation slip. While at high creep strain, it promotes the precipitation of nano-sized α particles, and dislocation slip hardly transfers across the α/β interface. WebHigh-temperature (creep) strength properties or creep causes permanent deformation of materials due to high mechanical stresses if subjected to heating for a long time …
Web13 de jul. de 2024 · The creep rupture test (stress rupture test) is used to measure the high-temperature strength of materials that are subjected to constant stress at elevated … Web17 de ago. de 2024 · Our reasoning was that, to make a case for RHEAs as viable high-temperature materials, creep-relevant properties, and not just yield strength, must be measured. We show here that the TiZrHfNbTa RHEA is dramatically weaker in creep than a leading precipitate-strengthened Ni-base superalloy introduced in the 1990s, CMSX-4.
