Abstract
In the last fifty years, there has been a tremendous R&D effort devoted to the development of new high temperature materials. However, in several industries, particularly in energy, automobile, defence, chemical and aerospace sectors, there is an intense demand for new materials. This demand has inevitably led to the study of structural intermetallics for such applications, γ-based titanium aluminides are a class of intermetallics which are being tested for several applications, since they possess good strength to weight ratio and excellent creep and oxidation resistance. Alloy design principles have been used to optimize the properties of these alloys. These principles often have their origin in earlier research on steels and these analogies and recent examples of successful alloy design of intermetallics will be discussed. The basis of alloy design in γ-based TiAl alloys is described with examples.
