I feel sometimes myself like the Shepard in Alchemist. Though I don’t dream about pyramids, but I always grab opportunities to visit places whenever possible. This time it was Chennai, and NMD-ATM, annual technical meeting of metallurgist from all over India. Along with the meeting I actually wanted to visit IIT-Chennai. So now I have seen two IITs. ATM followed FDM, the international conference on future of materials where Atul presented a paper, and I was fortunate enough that he had put my name in it! Thanks Atul! Before ATM I have to mention NMD because on that day Dr. Phanikumar got the young metallurgist award and I want to congratulate him.
I heard before the conference that ATM is a low profile conference, but was elated to find that a portion of the talks were really good. The participation was really huge, posters as well as speeches. A whole gamut from materials and metallurgical research came here. Truly speaking conference was very general and I had to find talks of my own interest. There were three parallel sessions. I was especially interested in the mechanical behaviour of materials, some functional stuffs and then Ceramics of course. I had attended few sessions on mechanical behaviour of materials. First day, 15th Nov. I found some interesting stuffs about Spark Plasma Sintering processes. ARCI is currently doing lots of work on that, with Dibyendu around I would also try something! Guru’s rafting was as usual good and I guess serendipity is knocking his door. There was a talk by Vendervort, the king of metallography and also days end Vikram mesmiriesed audience with a 10 min talk on wear. Second day it was bit hectic, as I wanted to attend the talk on metallic glasses, it was interesting session, Krishanu presented his paper on non-equilibrium solidifation which was good, better was his answers ( Dr. Dey, from BARC showed some beautiful HREM micrograph of the metallic glasses, again the controversy begun whether there is crystallization at the shear bands, Prof Ramchandra Rao, pioneer in the field was also present there. Rejin, hurried through his beautiful talk! Just for attending Vikram’s lecture, but his experiments for exhibiting Ductile Brittle transition was really good. Vikram was fascinating in his talk on the amorphous ceramics. Its really a magic material only requires good magicians like prof. Jayaram.It was more like our class room, but I wasn’t happy with the explanation he tried to give in support to the densification at high temperatures. The nano grains grow so fast, it is really difficult to differentiate between densification, creep and grain growth processes. I would be unfair If I miss the last talk which a girl from IGCAR delivered. They were using Infrared camera for strain measurement during tensile experiment. Not only the local strain it was possible to measure the stress distribution in the specimen, for large component which may be a good tool to use, but what I understood is that there are limitations in the shape of the resolution of the camera.
Its like writing a summary of Ramyana, I would have loved to describe each of the talks I participated but that’s some other time. What I really want is to thank all the faculty staffs and students, from IIT Chennai, life were really tough for them in that last week.
