Web31 de dez. de 2001 · The creep behaviour of directionally solidified (DS) Ni-base superalloy GTD 111 has been investigated at various temperatures (649 °C to 982 °C) and stresses … WebAdding fibers will increase the creep resistance. Carbon fiber filled PEEK will still not outperform unfilled PAI at 150°C in terms of creep resistance. For example, PEEK with 30% carbon fiber shows at 100°C a better creep performance as unfilled PAI. At 150°C, this turns around and PAI has the better creep resistance.
WebCreep is a very important phenomenon if we are using materials at high temperature. Creep is very important in power industry and it is of the highest importance in designing … Webhigh-temperature strength properties should be given priority; creep or creep-rupture (sometimes called stress-rupture). If the component is small and/or the tolerances very close, such as in turbine blades, creep is regarded as the overriding factor. But if the component is large and capable of accommodating greater deformation, such as shell-and-
Web11 de abr. de 2024 · In general, the creep strain is achieved by the competitive result of work hardening and dynamic recovery. Thus, a high creep resistance can be fulfilled under the condition of a strong work hardening effect provided by the strong entanglement of high-density dislocations in 1Mn samples [[29], [30], [31]].
