Metallurgy

IIT, Roorkee metallurgical and materials engineering has been in existence since long and with alumni in Los Alamos National Lab, Bell Lab, Microsoft Research and many more. Moreover, the culture of inter-disciplinary research along with the presence of Centre of Excellence - Nanotechnology, which is headed by a professor of metallurgical and materials engineering, you get the added advantage to work in the best of the labs. It has the best of metallurgy, important for GATE and PSUs, and materials science, the forward science of research today. A four year course always works to your advantage and you can further do your Masters only if you are serious about research or learning in particular. Hence, choose wisely, though inclination is towards IIT, Roorkee.
All the best.

Bachelor of Technology in Structural Engineering is a 4- year undergraduate course offered by institutes/universities for specialisation in Civil Engineering. Candidates who have successfully completed 10+2 or equivalent education are eligible to apply for this course. Admission to the course can be obtained through entrance examinations that are conducted by such institutes. The average annual fee of the course is INR 150,000. Successful graduates of the discipline find employment opportunities in various sectors including residential and non-residential construction industries, trade contracting businesses, and industrial construction etc. With an average annual income of INR 3,00,000.

Scope of metallurgy is good whether it is in core or non core field. Non core field has already mentioned in other answers like you can be a business analyst, can go in consultancy companies etc. You can do MBA, IAS, MS, Mtch, MSc, Mphil etc. Many non core companies come for metallurgy as well in PEC. So in non core field you have a large scope.
Now moving on to the core field. First of all only those who have interest or whose interest build with time in metallurgy goes into core. Like in my batch only 4-5 were interested in core field out of 30 students. Scope:
1. Automobile companies need Metallurgical Engineer. Eg Maruti Suzuki
2. Construction companies like L&T need Metallurgical Engineer
3. Oil companies like Indian Oil needs Metallurgical Engineer
4. Iron & Steel industry needs Metallurgical Engineers in large number like Tata Steel, Steel Authority of India Ltd. (SAIL), Jindal Steels
5. Manufacturing Industry needs Metallurgical Engineer like foundry, forging, sheet metal companies etc.
6. There is a need of Metallurgical engineer in Bhabha Atomic Research Centre (BARC), NALCO, Bureau of Indian Standards, DRDO etc.
The list goes on.
So it depends on an individual, if one has the right direction and right zeal, he/she can do anything and everything.
