Texture in Materials

By Prof. Somjeet Biswas | IIT Kharagpur

Learners enrolled: 289

Dr. Somjeet Biswas is Associate Professor in Dept. of Metallurgical & Materials Engineering, Indian Institute of Technology, Kharagpur. He specializes in mechanics of plastic deformation in ultra-fine and nanocrystalline materials through polycrystalline plasticity simulations with specific applications in aerospace, automobile and degradable/permanent bio-medical implant applications. He has used microstructure engineering techniques like severe plastic deformation, thermo-mechanical processing and recrystallization to modify the morphological characteristics, texture and grain boundary to obtain ultra-fine grain metals and alloys that possess both improved strength and ductility and hold 35 publications and 04 patents. His thrust areas of research include the development of advanced lightweight and high strength Mg, Ti, Al alloys and steels. He and his team in the ‘Light Metals and Alloys Research Lab, MME, IITKGP’ is working on deciphering the effect slip/twin induced deformation behaviour, dynamic recovery and recrystallization on the evolution of dislocations, microstructure, texture and grain boundaries in order to improve specific properties based upon application.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 23 October 2021 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
