    Sir,
    in week 12 assignment question no. 6 there is a question " The surface modification process for a metal system which does not respond to the heat treatment, generally relies on " and the options given are
    Grain Refinement
    Mechanical working
    Precipitation hardening
    Both a and c
    but in the lecture 58 which you gave us, you said " The surface modification process for a metal system which does not respond to the heat treatment, generally relies on Work Hardening Methods. " The time was 23:36-23:43 and there is no option of Work hardening in the question.
    It will be very helpful if you look into this matter.
    Thank you

      Mechanical working . Which also comes under work hardening or strain hardening eg- shot blasting etc.
