The Effects of Interstitial Elements on the Phase Stability and Mechanical Behavior of Intermetallics.

Abstract

This document constitutes the final report for ONR sponsored research entitled. The Effects of Interstitial Elements on the Phase Stability and Mechanical Behavior of Intermetallics". Alloying with interstitial elements O, N, or C induced structural changes from the A15 crystal structure to the ordered fcc L1(sub 2) or L'1(sub2) structures in 16 alloy systems. The L1(sub 2) or L1(sub 2) structures exhibited higher fracture toughness values than those of the original A15 structure compounds. jg
