Abstract

ABSTRACT The γ/γ’ microstructure is a key factor for the mechanical performance of nickel-based single crystal superalloys. Experimental results have shown that the size and shape of the γ’ precipitates are not uniform and follow certain probability distributions. In order to study the effect of the microstructure on the mechanical behavior of the superalloys, a method is proposed to reproduce its initial microstructure with the distribution function of its γ′ particle size. The effect of different microstructures on the creep behavior at different locations of a real blade is predicted to demonstrate the application of the method. It can be found from the simulation results that the mechanical behavior of the blade is related to not only the thickness of the blade wall but also the position in the blade.

期刊介绍： Materials at High Temperatures welcomes contributions relating to high temperature applications in the energy generation, aerospace, chemical and process industries. The effects of high temperatures and extreme environments on the corrosion and oxidation, fatigue, creep, strength and wear of metallic alloys, ceramics, intermetallics, and refractory and composite materials relative to these industries are covered. Papers on the modelling of behaviour and life prediction are also welcome, provided these are validated by experimental data and explicitly linked to actual or potential applications. Contributions addressing the needs of designers and engineers (e.g. standards and codes of practice) relative to the areas of interest of this journal also fall within the scope. The term ''high temperatures'' refers to the subsequent temperatures of application and not, for example, to those of processing itself. Materials at High Temperatures publishes regular thematic issues on topics of current interest. Proposals for issues are welcomed; please contact one of the Editors with details.
