Abstract
This invention concerns a method for controlling the microstructure of directionally solidified eutectic articles and the article produced thereby. The method is particularly appropriate for the production of articles such as turbine blades which require different mechanical properties in different areas of the article. The microstructure is controlled by varying the directional solidification conditions during the casting process.
