AbstractAbstract
[en] For the last ten years, our group at the Indian Institute of Science has utilized ordered precipitates and minor alloying elements to develop alloys with attractive high-temperature properties, including strength, oxidation, and coarsening resistance. The underlying principles adopted for such development are a) introduction of alloying addition that yield coherent, ordered precipitates, b) ordered intermetallic compound that strengthens the alloy c) introduction of minor alloying additions that segregate at the interface to enhance the stability and strength of the precipitates and d) alloying additions that partition in the matrix and aid in reducing the diffusive flux and strengthen the matrix. We shall illustrate it by presenting recent results of a high specific strength cobalt-base alloy, a high strength Zr/Ta containing aluminium alloy and a high strength high conductivity copper alloy where the L12 ordered precipitates play an important role.
