A fast spreadsheet model for the yield strength of superalloys

Abstract

A methodology to rapidly evaluate the yield strength of superalloys using a fast spreadsheet model was explored. The results from a physics-based discrete dislocation simulation model were fit to polynomials. These were used along with appropriate heuristic logic, to develop a spreadsheet that can predict the yield strength from the composition, and microstructural parameters of an alloy. The model was compared with data available for a series of superalloys and found to have good correspondence.
