if there is no as such interest in particular branch then metallugical @IIT Kanpur wud be the best option for you ..As IIT K is one top three collages in India. Also the future in metaallrgy is great in terms of High end organizations Like BHEL, GAIL, ISRO , DRDO, BARC, and many other like SAIL, Jindal steels , Bhushan Steels ..
but there are not much requirements as comapare to other like electricals etc .. People from metallurgy prefer to got into research and pursue M Tech. If done from IIT chances of going out of india are also worth as outside inida like in germany , ukraine, france, russia ppl are recruiting metallurgy students..
At last i wud like say clear ur mind and think of what u love best. dont compromise on that coz u got to live with it all ur life..
All the best for your Future !!
