In studying the degradation experienced by alloys during their exposure to aggressive high temperature gaseous environments, thermodynamic considerations can give a good insight into which corrosion products may form as a result of the various gas/metal reactions. The purpose of this paper is to illustrate how an interdisciplinary approach, involving both the research scientist and the design engineer, has been successfully applied to this topic. A "Medusa" computer aided design (CAD) system has been used initially to construct the simpler binary phase stability diagrams direct from thermodynamic data much more quickly and efficiently than could be achieved by hand-drawing. Of much greater significance, however, has been the evolution from these 2-D line drawings to 3-D perspective diagrams and finally to the superimposition of rotated images thereby enabling stereographic projections to be made. These latter projections markedly improve the user's visualisation of spatial relationships.
