               The Department of Metallurgical and Materials Engineering (MME) is one of the oldest departments of IIT Madras, established in 1959 as Department of Metallurgy at the very inception of the Institute. The Department is actively engaged in research, education and industrial consultancy. It offers B.Tech, M.Tech, M.S. and Ph.D. degrees. The Departments teaching, research and consultancy activities cover a broad spectrum of materials science & engineering and industrial metallurgy (metal casting, metal joining, metal forming and materials technology). During the initial stages, the Department received generous support from Germany(erstwhile FRG). The Department developed a unique character at the outset owing to its strong linkages with the industry and the expertise of the faculty in industrial metallurgy. Over the years, the research interests of the faculty have diversified into many areas of materials science & engineering.

               The Department has excellent research infrastructure in the broad areas of materials processing (forming, joining, casting, particulate processing, nanostructured materials), characterisation (X-ray diffraction, electron microscopy, thermal analysis, scanning probe microscopy), mechanical testing, environmental degradation, surface engineering, and computational materials science.

Education 
               In the past three academic years (2005 to 2007), the Department has awarded 25 Ph.D., 17 M.S., 58 M.Tech. and 95 B.Tech. degrees, including Dual Degree B.Tech & M.Tech. Continuing education programmes for the industry and academia are conducted on a regular basis, mostly in collaboration with various professional organisations.

Publications
                The Departments faculty have the highest annual rate of publication in the Institute. Apart from journal and conference papers, the faculty members have made major contributions by authoring books and monographs, and serving as editors of prestigious national & international publications.

 

Patents
             Three patents have been awarded/filed based on the research by faculty members of the Department in the last three years. A total of 10 patents have been awarded since the Department was started.

Professional Activities
                The faculty and students are active members and, in many cases, office bearers of prominent professional societies such as Indian Institute of Metals, Indian Institute of Welding, Indian Society for Non-destructive Testing, Indian Welding Society, Society for Biomaterials and Artificial Organs (India), and A Society for Materials International. The Department hosts the local chapters of many of the above organisations. 
                The Department organises the International Symposium for Research Scholars every two years. This unique series of symposia started as the National Symposium for Research Scholars in 1996, and has become an international series since 2004.
