Use Of The Wilshire Equations To Correlate And Extrapolate Creep Data Of Inconel 617 And Nimonic 105, Vito Cedro Iii, Christian Garcia, Mark Render Dec 2018

Use Of The Wilshire Equations To Correlate And Extrapolate Creep Data Of Inconel 617 And Nimonic 105, Vito Cedro Iii, Christian Garcia, Mark Render

Mechanical Engineering Faculty Publications and Presentations

Advanced power plant alloys must endure high temperatures and pressures for durations at which creep data are often not available, necessitating the extrapolation of creep life. A recently developed creep life extrapolation method is the Wilshire equations, with which multiple approaches can be used to increase the goodness of fit of available experimental data and improve the confidence level of calculating long-term creep strength at times well beyond the available experimental data. In this article, the Wilshire equation is used to extrapolate the creep life of Inconel 617 and Nimonic 105 to 100,000 h. The use of (a) different methods …

Advanced power plant alloys must endure high temperatures and pressures for durations at which creep data are often not available, necessitating the extrapolation of creep life. Many methods have been proposed to extrapolate creep life, and one of recent significance is a set of equations known as the Wilshire equations. With this method, multiple approaches can be used to determine creep activation energy, increase the goodness of fit of available experimental data, and improve the confidence level of calculating long-term creep strength at times well beyond the available experimental data. In this article, the Wilshire equation is used to extrapolate …
