Abstract : A visit to DMRL coincided with the Workshop on Structural Intermetallics - Perspectives on Science and Technology, 5-6 February, which was sponsored by the Materials Research Society of India, and co-sponsored by the AOARD Conference Support Program (CSP). DMRL acted as the host of the workshop. The purpose of the workshop was to assess the current trends in the application of intermetallics for structural applications. There were a total of 22 papers presented, eight from foreign invited speakers, covering structural intermetallics. Most of the talks, in line with the theme of the workshop, focused on applications and technical challenges for structural intermetallics. The alloy systems discussed included Ni3Al, NiAl, Ti3Al, TiAl, Fe3Al, Fe-Al-X, and Zr3Al. Most of the research in India on intermetallic compounds has focused on alpha-2 Ti3Al- based alloys, and more recently on the orthorhombic alloys based on Ti3Al-Nb. The orthorhombic alloys have received attention in the last several years, due in part to the inadequate oxidation resistance of the classic alpha-2 alloys. jg p.3
