Abstract
The effect of carbon on the mechanical properties of ordered, face-center-cubic Ni3Al has been studied. It has been found that carbon provides no ductihzation to the intermetallic compound, but exerts a large solid solution strengthening effect. The strengthening rate measured is Δσy/ΔC∼0.5G per atom percent carbon, where G is the Ni3Al shear modulus. Auger analysis and lattice parameter measurements were also carried out. The results are discussed with respect to the nature of carbon in grain boundary regions and in the bulk.
