Defects Associated with Soldification of Melt Processed Superalloys for the Aerospace Industry
Abstract
This Materials Engineering for Affordable New Systems (MEANS) program centered on developing an integrated computational framework for predicting the conditions under which turbine blades can be produced that are free of deleterious solidification defects. To achieve this ambitious goal we studied the solidification process over length scales from subnanometer to millimeter with the goal of producing a theory for defect formation. Three dimensional datasets have been acquired to study the details of the fluid flow process. Close interaction with industry was essential to ensure the resulting computational model will be in a form that is usable in their efforts to design new alloys and processing routes. Given the broad research focus of the project the MEANS team was composed of engineers and scientists from government laboratories, industry, and universities and is diverse in its research expertise.
