DIRECTIONALLY SOLIDIFIED GAMMA-GAMMA PRIME EUTECTIC ARTICLES FOR HIGH TEMPERATURE USE

摘要

ABSTRACT OF THE DISCLOSURESpecific eutectic alloy compositions in the Ni-Al-Tasystem are disclosed along with processing techniques toproduce a directionally oriented microstructure. Articlesproduced according to the invention have good high temper-ature properties and are suited for use in gas turbineengines.
