A Fundamental Understanding of the Interfacial Compatibility in Hybrid Material Systems

Abstract

Among the problems associated with long term high temperature service of hybrid material systems is interdiffusional compatibility of the system's component materials. Efforts in this program have focussed on several areas of this problem. One of these areas being examined is the use of alkali and alkali earth metals for diffusion barriers. These barriers are being applied by ion implantation. The model system being used is the W/Ni system. Preliminary results of barrier effectiveness are given. Also being studied intermetallic/ intermetallic ternary systems. Hybrids being examined include W/Ni3Al and Ni3Al/ TiAl. Intermetallic compounds.
