Analysis of high-temperature creep deformation in a polycrystalline nickel-base superalloy
Abstract
A new quantitative method has been developed for the analysis of the high-temperature creep deformation of polycrystalline nickel-base superalloys. Local deformation was measured by means of microextensometry using ceramic square grids deposited on flat specimens thanks to an electron lithography technique. The efficiency of this method has been proved for tensile creep tests performed under vacuum at 750°C and 525MPa on the NR6 superalloy and …
