A Fundamental Understanding of the Interfacial Compatibility in Hybrid Material Systems

Abstract

Efforts in this program have focused on developing an understanding of the nature and kinetics of component interactions in hybrid material systems at elevated temperature. Previous work on the chemical interactions in tungsten fiber reinforced superalloys was expanded on to include the effect of matrix chemistry on fiber recrystallization kinetics. General studies to assess the kinetics and diffusion path behavior of metal intermetallic (W/Ni3A1) and intermetallic intermetallic (TiAl/Ni3Al) were also undertaken. A feasibility study for production of diffusion barrier layers via ion implantation were also conducted. In response to a controversy in the scientific community, the influence of fiber matrix interactions on the anomalous creep behavior of SiC/Al was investigated.
