We have recently shown that cobalt alloys with a basic composition of Co-10Al-5Mo with quaternary additions of Nb or Ta can, after heat treatment can generate ’ microstructure similar to nickel-based superalloys with no penalty on density. The present paper updates the current development in our group on the effect of alloying additions and their effect on the stability of the microstructure after long-term exposure at different temperatures. This also includes physical and mechanical properties of these alloys such as thermal, electrical and magnetic properties and the creep properties. The suitability of these alloys at different environments is also being studied and the results available will be presented. Finally, we shall, on the basis of the available experimental data, evaluate the possible application domain of this class of alloys and the further challenges that need to be overcome in taking this class of alloys further.
