creep rateaustenitic steelcarbideprecipitationMany microstructural changes take place in heat-resisting steels and alloys at high temperature and affect their creep deformation behavior. In the present research, the effect of carbide precipitation on creep rate has been investigated for 10Cr-30Mn ...
Furthermore, a mechanical model coupled with oxidation scale growth was proposed to predict the deformation rate of the miniature three-point specimen which could agree well with the experimental results. 展开 关键词: creep and stress rupture mechanical oxidation steel ...
Using nanoindentation technology, the creep behavior of P92 steel welded joint that had experienced creep-fatigue (CF) loading was studied at the nanoscale. In both as-welded and CF samples, the fine-grain heat affected zone region exhibited relatively lower hardness and lower creep resistance than...
Dependence of Creep Rate on Pre-strain Rate in a Conventional Low Alloy SteelEXPERIMENTS have been made on ICr.Mo.V. steel isothermally heat treated to produce ferrite-pearlite and bainite structures to determine the effect of pre-strain and pre-strain rate on the subsequent creep behaviour....

The Relation between Creep Rupture Time and Minimum Creep Rate of Austenitic Stainless Steel 来自 Semantic Scholar 喜欢 0 阅读量: 50 作者:T Kawasaki,M Horiguchi 摘要: An attempt is made to explain the growth process of creep cavities wherein the diffusion mechanism is not applicable. When a ...
We performed elastic-plastic-secondary creep finite-element (FE) analysis of Gr91 (ASTM A387 GR91 CL2) steel using the properties at 565 °C to investigate the evolution of stress and strain rate at the weakest location of the SP creep specimen, i.e. at the annular region located at ...
decreases growth rate of the precipitate during creep exposure, which in turn increases the stability of the martensitic lath structure of the steel on creep exposure [7–19]. In the present investigation, creep deformation and rupture behaviour of 9Cr–1.8W–0.5Mo–VNb steel have been studied...
As the complex relationships between fracture life and its influencing factors can be well explained by the mean strain rate at half-life, which is considered as the main factor associated with the fracture life. Moreover, based on the ductility exhaustion theory and the effective stress concept,...
