The Effect of Iron, Gallium and Molybdenum on the Room Temperature Tensile Ductility of NiAl

Authors: R. Darolia; D. Lahrman; R. Field; GE AIRCRAFT ENGINES CINCINNATI OH ENGINEERING MATERIALS TECHNOLOGY LABS
Abstract:
Tensile tests were performed in air at room temperature and strain rate 8.3 X 10-5/s on , , and NiAl single crystals containing ternary additions of Fe, Ga, and Mo (0.05-2.0 at.%). At small alloying levels 0. 1-0.25 at.%, ductility of the and single crystals improved significantly. At higher alloying levels the ductility improvement was less pronounced. Considerable scatter in the data was observed for the hard orientation.
