1. Study of Ni3Al- and MoSi2-based Materials for High Temperature Structural Applications
Abstract : In general, the potential of current conventional high-temperature materials has been exploited to a large extent. The industries are therefore looking forward to development of alternative materials for their industrials application, which would be lighter, stronger and having improved higher temperature potential compared to the presently available alloys.

2. Oxidation of Fe- and Ni-aluminides in Dry and Humid Atmospheres
Abstract : Aluminides based on Ni3Al and Fe3Al offer good mechanical and corrosion properties at high temperatures and are therefore being considered in the automotive and chemical industries. The aim of this work was to study the early stages and the mechanisms of oxide growth on unalloyed Ni3Al and Fe3Al in air. READ MORE
